Three different objects of masses ${m_1},{m_2}$ and ${m_3}$ are allowed to fall from rest and from the same point $‘O’$ along three different frictionless paths. The speeds of the three objects, on reaching the ground, will be in the ratio of

A

${m_1}:{m_2}:{m_3}$

B

${m_1}:2{m_2}:3{m_3}$

C

$1:1:1$

D

$\frac{1}{{{m_1}}}:\frac{1}{{{m_2}}}:\frac{1}{{{m_3}}}$

(AIIMS-2002)

Solution

(c) Speed of the object at reaching the ground $v = \sqrt {2gh} $

If heights are equal then velocity will also be equal.
