Assuming potential energy ‘U’ at ground level to be zero. All objects are made up of same material

Question 1

Assuming potential energy ‘U’ at ground level to be zero.

All objects are made up of same material.

UP = Potential energy of solid sphere

UQ = Potential energy of solid cube

UR = Potential energy of solid cone

US = Potential energy of solid cylinder

(A) US > UP

(B) UQ > US

(C) UP > UQ

(D) UP > US

Question 2

Correct option (A) (B)

Explanation:

In P, Q and ; the centre of masses lie at D/2 height from the base level. Where as in R(cons) the com *** at D/4 height from the base.

Hence UP > UQ .
