Question

a stone 'X' of mass 2 kg at the height of 4 m from the ground level. another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground level. what is the differences between their potential energy.

Answer 1

Explanation:

as we know , P.E =MGH

p.e directly proportional to mass, height

therefore, Y has more mass than X so it's potential energy remains high than first stone ..

Answer 2

Answer:

80J

Explanation:

Given:-

Mass of stone1= 2kg

Height of stone1= 4m

Mass of stone2= 4kg

Height of stone2= 4m

Potential Energy= m*g*h (m= mass, g= acceleration due to gravity, h= height of the object)

P.E.1= 2*10*4= 80J  [Potential Energy of 1st stone]

P.E.2= 4*10*4= 160J  [Potential Energy of 2nd stone]

Therefor difference between their P.E. = 160J-80J= 80J
