To what height should a body of mass 5 kg be raised so that its potential energy is 490 J? [g = 9.8 m/s2]

The potential energy due to gravitation is given by

P.E = mgh


Where, m = Mass,


G = acceleration due to gravity,


H = height,


Given


Mass = 5 Kg,


P.E = 490 J,


G = 9.8m/s2.


H =?,


490 = 5×9.8×h



Hence the body should be raised to 10 m
