Two identical spheres `A` and `B` are free to move and I, rotate about their centres. They are given the same impel `J`. The lines of action of the impulses pass through tht centre of `A` and away from the centre of `B`, then

Options

A. `A` and `B` will have the same speed
B. `B` will have greater kinetic energy than `A`
C. they will have the same kinetic energy, but the Linear kinetic energy of `B` will be less than that of `A`
D. the kinetic energy of `B` will depend on the point impact of the impulse on `B`

Answer

A, B, D

Explanation

`J=mv` for both sphere `A` has no angular motion. For sphere `B` angular momentum imparted by `J=L=Jh`.
