Question

The potential energy E of a body depends upon its mass (m) , acceleration due to gravity (g) and
height (h). Using dimensional analysis derive relationship between them

Answer 1

Answer:

sorry boss I don't know..

Answer 2

Dimension of Potential Energy is ML^2T^-2  

P.E. = mgh  

m = mass  

g = acceleration due to gravity  

h = height  

Dimension of mass = M  

Dimension of acceleration due to gravity = LT^-2  

Dimension of height = L  

mgh = M ×LT^-2 × L  

= ML^2T^-2  

Hence P.E. = mgh
