Question

A solid sphere is moving and it makes an elastic collision with another stationary sphere of half of its own radius. After collision it comes to rest . The ratio of the density of material of second sphere and first sphere is

Answer 1

ratio if density will be 8

Answer 2

Answer:

Explanation:

Since the first body comes to rest after colliding with a another stationary body masses of both the bodies are same so m1=m2

Now m1/v1:m2/v2=v2/v1

R(cube)/(r/2)cube

=8
