A body of 10 kg is falling from the height of 50m under the influence of gravitational force. Then the work done is $\left(\text{g}={\text{10ms}}^{-\text{2}}\right)$

$\text{mass of the body m}=\text{10kg}$

$\text{Displacement S}=\text{50m}$

$\text{Acceleration due to gravity g}={\text{10ms}}^{-2}$

  $\text{Work done W}=\text{F.S}$

  $=\text{mg s}$

  $=10\times 10\times 50=5000$

  $\text{W}=\text{5000J}$
