Calculate the work done in moving a body of mass 50 Kg through a height of 5 m.$(g=10\ m/s^2)$ a). 250 J b). 2500 J c). 25 x 103 J d). 2.5 x 105 J

Academic Physics NCERT Class 9

Here, the mass of the moving body $m=50\ kg$

Height of the moving body $h=5\ m$

Gravitational force $g=10\ m/s^2$

Therefore, work done in moving the body $=mgh$

$=50\ kg.\times10\ m/s^2\times5\ m$

'$=2500\ Joule$

Therefore, option b). is correct.
