Acceleration due to gravity in vacuum is same irrespective of size and mass of the body

Vedclass · Answer

(A) The equation of motion for an object falling from rest from a height $h$ is given by $h = \frac{1}{2}gt^2$,where $g$ is the acceleration due to gravity and $t$ is the time taken.Solving for $t$,we get $t = \sqrt{\frac{2h}{g}}$.In a vacuum,there is no air resistance,and the acceleration due to gravity $g$ is independent of the mass and size of the falling object.Since both balls are released from the same height $h$ and experience the same acceleration $g$,the time taken $t$ to reach the ground will be the same for both.Therefore,the correct option is $A$.

An iron ball and a wooden ball of the same radius are released from a height $h$ in vacuum. The time taken by both of them to reach the ground is equal based on:
