Find the ratio of potential energy if an object is raised to thrice of its height and its mass is tripled.(a) 1:1(b) 1:4(c) 1:9(d) 1:3The question was posed to me in unit test.This interesting question is from Potential Energy topic in division Work, Energy and Power of Physics – Class 11

Answer»

Correct answer is (c) 1:9

To ELABORATE: PE1 = m x G x h

PE2 = (3M) x g x (3H)

 = 9 x m x g x h

PE1 : PE2 = mgh : 9mgh

 = 1:9.
