Question
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
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
Options
A.US > UP
B.UQ > US
C.UP > UQ
D.US > UR
Solution
PE of solid sphere
= mgR = mg
= ρgD4
PE of solid cube = mg = ρgD4 
PE of solid cone = mg
= ρgD4 
PE of solid cylinder = mg = ρgD4
= mgR = mg
= ρgD4PE of solid cube = mg
= ρgD4 PE of solid cone = mg
= ρgD4 PE of solid cylinder = mg = ρgD4
