By what acceleration the boy must go up ...

By what acceleration the boy must go up so that `100kg` block remains stationary on the wedge. The wedge is fixed and is smooth `(g =10m//s^(2))`
.

Text Solution

Verified by Experts

The correct Answer is:
633
By the definition of inertial an non-inertial fram
`50 (10 +a) = 100 xx 10 xx (4)/(5) rArr a = 6ms^(-2)` .
