Question

if gravitational potential energy of body at the surface of earth is E0 what will be its potential energy at height H from surface
A) mgh
B)mgh - E0
C) mgh + E0
D)EO - mgh

Pls answer​

Answer 1

Answer:

mgh

Explanation:

At the surface of the earth h(height of elevation) is 0. The expression for gravitational potential energy = mgh.

m×g×0=0.

Therefore, at height 'H' the gravitational potential energy of the body of mass 'm' will be mgh.

Hope this is helpful.

Answer 2

Answer:

mgh-Eo

Explanation:

we calculate change in gravitartional potential energy

♡U = mgh ÷ ( 1+ h/R )

this is the actual formula to calculate change in gravitational potential energy

Since h is considered as small value in comparision to R in the given problem so we choose it as mgh

Ufinal - U initial = mgh

Ufinal = mgh + U initial

Ufinal = mgh + Eo
