calculate the gravitationlal potential energy of a body of mass 400g when it is lifted to a height of 4m above the ground
Asked by mithilgowda33 | 15 Dec, 2021, 10:13: PM
Expert Answer
P.E. = mgh
m = 400 g = 0.4 kg
g = 9.8 m/s2
h = 4 m
Thus,
P.E. = 0.4 x 9.8 x 4 = 15.68 J
Thus, the gravitationlal potential energy of a given body at height 4 m is 15.58 J
