we can assume a centrifugal force which is like balancing condition to tension, at first le mw^2r=t but after some time r is varying so the a net force , due to which is being pulled in tangential direction also, another thing could be that theta is varing so because of that it is getting a tangential force. (theta is with the horizontal) idk man I tried.

May be ball ki center directional velocity increase ho rahi hai jiski dicrtion change nahi hogi baad mai but jab ball ghumegi toh wahi velocity uski tangential wali velocity se over lap kar rahi ho or velocity tengent wali bda rhi ho, is it correct? Ho sakta hai message mai confusing lage
What I thought I can relate this question with the basic example that is usually taken in class i.e when A man spins around himself initially keeping his both hands away and then take his hands inward and then his speed increases, so moment of inertia depends on mass distribution too, and since angular momentum is conserved therefore tangential speed increases. Qoura answer Since radius is decreasing the path isn't perfectly circle at all time, so Tension is not perpendicular to radius all time so therefore tangential speed increases
Nope.... Although Tension is not perpendicular to net velocity (=tangential vel vector + radial vel vector), Tension is always perpendicular to tangential velocity.
Net velocity is not perpendicular to tension …. May be tension is changing net velocity.. uski wjh se tangential component of velocity increase ho rha h
When the ball is on spiral inward motion and the moment when the radius of circular path decreases at that point tension is not perpendicular to the tangential velocity
I think this is the answer : please correct if I am wrong. In this case there is no torque about the point of rotation so the angular momentum is constant and since L is constant , with decrease in radius , there is increase in speed(v) . The speed is increasing without any tangential force because the tension force (centripetal force) is increasing
But where is the answer in what u have written? Torque=0, hence LOCAM gave us that tangential velocity will increase. But there is no tangential force. This thing should make one uncomfortable. Now try invoking all ur concepts to sort this thing out. Tension provides centrifugal force; no tangential force present. Then how is tangential velocity increasing!!?
@@DarshIITB Bhaiya please answer bata do I have to tried my best but couldn't figure it out. I feel This problem is somewhat similar to the situation where the velocity of an object increases when it loses mass like a rocket. There also, velocity increases without any additional force. Very curious to know the answer.
The differentiation is incorrect. V is a vector and while diffferentiating you have only differentiated the magnitude. Must also consider the rotation aspect of the vector.
bhaiya aisa analizing power develop kaise kare , aur aisa soch to lete ha ,but inka answer khud se kaise nikalenlike ; asia hi kyu hua, ye kyu nahi ho sakta; matlab inka answer khud se kaise find kare
The ball is moving in circular path and it is getting closer to the center. Now we can take 2 points(in that spiral path) which are close and try to analyse the motion between these points, Then the velocity vector do not always point toward center(as velocity is tangent to that path), so a component of tension can be drawn in the direction of velocity vector, thus increasing its speed. Am i correct ???
Bhai ,,I thought tangential velocity is not actual velocity that is the component of actual velocity,,,and actual velocity is the net velocity of radial and tangential velocity.........
The concept of this tangential force is similar to the concept of pseudo force. It isn't naturally acting on the body but we apply it for our convenience so that Newton's law (F=ma) is valid.
Yes bcs when we write s = r cos@ i + r sin@ j and differentiate this to get w by applying uv rule. And then obtain angular acceleration by differentiating again. We get a component in the tangential direction as well
May be while covering the spiral path the tension might not be perfectly perpendicular to the direction of motion of ball due to which there is some component of tension in tangential direction which is producing tangential acceleration

The change in Angular Momentum Creates a Torque which is Responsible for the tangential Acc of the mass M
There is no change in angular momentum. Torque about orig = 0
Very effective.
we can assume a centrifugal force which is like balancing condition to tension, at first le mw^2r=t but after some time r is varying so the a net force , due to which is being pulled in tangential direction also,
another thing could be that theta is varing so because of that it is getting a tangential force. (theta is with the horizontal)
idk man I tried.
about the centre, torque is zero…. so angular momentum should be conserved. so i think thats why omega is increasing..

The avg acceleration Vfinal-Vinitial/T has one component along tangential direction maybe that's the reason
