1.

A particle starts from rest from point P and follow a path PQ on the three smooth surfaces as shown in figures. If time taken by the particle in three cases are `t_(1), t_(2)` and `t_(3)` then A. `t_(1) gt t_(2) gt t_(3)`B. `t_(3) gt t_(2) gt t_(1)`C. `t_(3) gt t_(1) gt t_(3)`D. `t_(1) = t_(2) = t_(3)`

Answer» Correct Answer - B
`L = (H)/(sin theta) = (1)/(2)g sin theta xx t^(2)`
