To what height should an object of mass 2 kg be raised so that its potential energy is 980 J?(Take, g = 9.8 ms−2)
50 m
Potential energy is mathematically represented as P.E. = m×g×h ,
where m is the mass,
g is the gravitational acceleration and
h is the height from the ground.
On substituting the values, we get:
980=2×9.8×h
h = 50 m
