Question

Obtain an expression for gravitational P.E. Of a body.

Answer 1

∆U =mgh ,∆U=Gmm÷r, is the formula for gravitational potential energy

Answer 2

Answer:

U=mgh

Explanation:

let m be the mass of the body

g be the gravitational acceleration

and h be the distance of the body from the ground

U be the P.E. of the body

U of the body is equal to work(W) done to bring the body at that height

W =FS (F=FORCE ANDS IS DISPLACEMENT)

F=mg

S=h

therefore,

W=mgh

U=W=mgh

therefore

U=mgh

Hope this would help you.
