A 10kg object is raised to a height of 20m. What is the magnitude of its potential energy? (Assume g = 10 m/s^2)

(a) 500 J

(b) 1000 J

(c) 1500 J

(d) 2000 J

I had been asked this question during an online interview.

My query is from Potential Energy in portion Work, Energy and Power of Physics – Class 11

The correct answer is (d) 2000 J

To explain I would say: PE = m x g x h

m = 10 kg

g = 10 m/s^2

h = 20 m

PE = 10 x 10 x 20

= 2000 J.
