Question

A sphere collides with another sphere of identical mass. After collision, the two spheres move. The collision is inelastic. Then the angle between the directions of two spheres is

• A. 45$^\circ$
• B. different from 90$^\circ$
• C. 90$^\circ$
• D. 0$^\circ$

Answer 1

Answer: (B)

different from 90$^\circ$

Answer 2

The collision is given to be inelastic and the spheres of same mass move after collision. The angle between the two direction will be different from 90$^\circ$.
