Question

When two particles each of mass 'm' are dropped from height 'h' and '2h' respectively, then ratio of their to reach the ground is

Answer 1

the ratio of time and velocity is the same if then (ratio h:2h)

Answer: 1:√2

Explanation:

time taken for a object of mass m from height h = $\sqrt{2gh}$

velocity for an object of mass m from height h = $\sqrt{2h/g}$
