Three different objects of masses `m_(1) , m_(2)` and `m_(2)` are allowed to fall from rest and from the same point `O` along three different frictionless paths. The speeds of three objects on reaching the ground will be:A. `m_(1):m_(2):m_(3)`B. `m_(1):2m_(2):3m_(3)`C. `1:1:1`D. `(1)/(m_(1)):(1)/(m_(2)):(1)/(m_(3))` |
