Answer:
P.E = 196 J
Step-by-step explanation:
Given,
The mass of the box, m = 10 Kg
The height of the box from the ground, h = 2 m
The acceleration due to gravity, a = 9.8 m/s²
The gravitational potential energy of the box is given by the formula
P.E = mgh joules
Substituting the given values in the above equation,
P.E = 10 x 2 x 9.8
= 196 J
Hence, the gravitational potential energy of box, P.E = 196 J
