Three different objects $m_{1}, m_{2}$ and $m_{3}$ are allowed to fall from rest and from the same point $O$ along thrce different frictionless paths. The speeds of the three objects, on reaching the ground, will be in the ratio of
- $m_{1}: m_{2}: m_{3}$
- $1: 1: 1$
- $m_{1}: 2 m_{2}: 3 m_{3}$
- $\frac{1}{m_{1}}: \frac{1}{m_{2}}: \frac{1}{m_{3}}$
The Correct Option is B

Concepts Used:
Motion in a straight line
The motion in a straight line is an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. It is nothing but linear motion.
Types of Linear Motion:
Linear motion is also known as the Rectilinear Motion which are of two types:
- Uniform linear motion with constant velocity or zero acceleration: If a body travels in a straight line by covering an equal amount of distance in an equal interval of time then it is said to have uniform motion.
- Non-Uniform linear motion with variable velocity or non-zero acceleration: Not like the uniform acceleration, the body is said to have a non-uniform motion when the velocity of a body changes by unequal amounts in equal intervals of time. The rate of change of its velocity changes at different points of time during its movement.
