Answer 2

give and mass of two balls a and b = m and 2m

density of two balls a and b= 2v and v

moment of inertia of sphere = (2/5)M *R^2

if the radius R of two ball is constant

then

moment of inertia of A /moment of inertia of B = Mass of A/mass of B = m/2m = 1/2

so

moment of inertia of A is 2 times the moment of inertia of B

b) we know that momentum = mass *velocity

so momentum of A /moment of B = 2mv/2mv = 1/1

momentum of A is equal to momentum of B

c) We know that

F = ma

and

to stop body v = 0

intiel velocity of A and B = v and 2v

let time taken by both body be t

so

v = u + at

a = - u/t

For A and B

Fa/Fb = (- 2mv/t )/(- 2mv/t)

Fa = Fb

both the body need same amount of force to stop since both force are equal.
