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)` |
