Question

A particle mass `m = 0.1 kg` is released from rest from a point A of a wedge of mass `M = 2.4 kg` free to slide on a frictionless horizontal plane. The particle slides down the smooth face Ab of the wedge. When the velocity of th ewedge is `0.2 m//s` the particle in `m//s` relative to the wedge is :-

A. `4.8`
B. `5`
C. `7.5`
D. `10`

Answer 1

Correct Answer - D
`COLM : - MV + m (v cos 60 - V) = 0 rArr v = 10 m//s`
