17:51 Sir, Gravitational force affects only the things with mass. Light has no mass, then how is it affected by gravitational force of the black hole????????????????

[@KrishnaTiwari-bp5zw]

Exceptionally Interesting and Fabolous session.

Hi sir

True

Unit of g is Newton because it is also a force

[@akshatpandey759]

We applied push or pull on the object is called force

[@fadwakm563]

It's better if it's taught in English so that everyone understands

[@sarasadiq738]

can there be up thrust in gases too? as you have used the term fluids.

[@harrypotterinwell]

One Doubt..
Is buoyancy and net force same???

[@harrypotterinwell]

no
buoyancy is the tendency of a liquid to exert an upward force on an object immersed in it
net means overall so net force means overall force

Sir i can't understand the 2nd question of menti 😔

[@lucysharmasurya1770]

😊pyr❤❤❤❤🏴‍☠️

[@architatayal7996]

Sir pls pls explain Q 2

[@abhay-u2f]

You have a query in this question

[@dishabhatt6936]

If you are asking about Menti 2nd question :
Let Mass of Planet 1 = M1 and Radius of planet 1 = R1
Let Mass of Planet 2 = M2 and Radius of planet 2 = R2
Given : Ratio of mass = 1:2 and ratio of radii = 1:2
M1 = 1, R1 = 1 , M2 = 2 and R2 = 2
Let g1 be acceleration due to gravity on Planet 1
g1 = GM1/(R1)^2 [ derivation of this formula is in video ]
Similarly g2 is acceleration due to gravity on Planet 2
g2 = GM2/(R2 )^2
We have to find g1/g2
g1/g2 = GM1/(R1)^2 / GM2/(R2) ^2
= 1/1^2 / 2/2^2 [ G is constant and it gets cancelled . I have substituted values of M1,R1,M2 and R2]
= 2/1
Therefore g1 : g2 = 2: 1
Hope this helps
