Question

The uniform acceleration experienced by a freely falling body is

• A. deceleration due to gravity
• B. acceleration due to gravity
• C. acceleration due to magnetism
• D. deceleration due to magnetism

Answer 1

Answer: (B)

acceleration due to gravity

Gravitational force between two bodies $m_1$ and $m_2$ is given by,
$F=G{m}_1{m}_2/R^2$
Considering $M$ as mass of earth, we get,
$m_{2}g=GM{m}_2/R^2$, where R becomes the radius of earth.
So acceleration due to gravity on $m_2$ will be
$g=GM/R^2$
This is the acceleration due to gravity.
