Question

Two masses of 100 kg and 1000 kg are separated by 1 m distance. Find the gravitational potential at the
mid point of the line joining them.​

Answer 1

Mass M1 =100kg

M2 = 1000kg

r =0.5m

So Gravitational Potential = -GM

r

= -GM1 - GM2

r r

= -G (M1 + M2)

r

= -G ( 100 +1000)

0.5

= -1100G

0.5

= -11000G

5

= -2200G is the answer at the mid point...

Hope it helps you...
