Sir please main abhi abhi class 12th mein aaya hoon, Mujhe kya karna chahiye, mujhe one shot videos dekh kar chapter complete karne chahiye ya poora depth mein se phadna chahiye. Sir poora chapter ke videos dala kro
Thank you sir for uploading at the right time My school is taking this chapter right now and with your explanation I don't have any doubts...... And sir can you please upload the ncert solutions of chapter 10 because my school has finished and also sir I have exam on next month so I am asking ...... If u can plzzz upload soon....
1.A stone is tied to one end of a string and whirled in a horizontal circle of radius 1m at 20 revolutions per minute. Calculate the angular velocity and linear speed of the stone. Also find the centripetal acceleration. 2. A force of 10N acts for 20 second on a body of mass 2 kg initially at rest. Calculate the energy required by the body and the work done by the applied force. 3. If the earth has a mass of 9 times and radius twice of the planet mars, calculate the maximum speed required by a rocket to pull out of the gravitational force of mars. Escape speed for an object on the surface of the earth is 11.2 km/s. 4. Calculate the change in volume of an iron block 10cm×20cm×5cm if it's temperature is raised from 10°C to 40°C. Given, coefficient of linear expansion of iron = 1.2×10^-5/°C. 5. A body of 0.25 kg executes SHM given by y=0.4 sin 0.5πt m. Calculate the amplitude ,angular frequency, maximum velocity and maximum acceleration.
Sir what do we mean by the energy of a charge???? I think energy is something by which we can do something work or displace anything, and In the case of a charge, it can interact with any other charge or can displace any positive or negative charge because of its electric field then can we say that energy of a charge is its Electric field or its ability to move any other, Am I right sir????🤔🤔🤔🤔
Sir jaise hum normal mathmatics mein points ko represent karne ke liye (x,y,z) cordinates ka istemaal karte hain vaise hi physics mein vectors ko represent karne ke liye (x^i, y^j and z^j ) ka use karte hain, Am i right 🤔🤔🤔??? And why the square of a unit vector is 1 🤔🤔🤔????

Very nicely explained
Thanks
Very helpful
Thanks
The language killed me 😭😭
Thanku sir
Welcome 🤗
Well explanation❤
College teachers also do not explain like this
Thanks 😊
Sir agar main khata hoon ki 2 meter toward x-axis then it is scalar or vector
🤔🤔🤔🤔
Vector

@@PhysicswithGaurav ok sir
Dear student, if you have doubt , then I will solve for you, but complete chapter is not possible right now
@@PhysicswithGaurav okk sir
If I have any doubts i will ask you
this question is from which book please reply
Excuse me sir I had few questions of first PUC in which I have doubt about the answers could you please solve it sir, it would be of great help
Yes dear student, write the statements in comment

Am I right sir????🤔🤔🤔🤔
Yes dear student, you are right, that’s why we say that energy is stored in capacitor as a form of electric field

Yes dear student, you are right.
Unit means = 1,
