Two bodies of masses $10 k g$ and $100 k g$ are separated by a distance of $2 m$ . The gravitational potential at the mid-point of the line joining the two bodies is:

Options:

Answer:

Solution:

As we know, gravitational potential

$V = \frac{- G M}{R}$

Gravitational potential at mid point,

$= - \frac{G \times 10}{1} - \frac{G \times 100}{1} = - 110 G$

$= - 110 \times 6.67 \times 10^{- 11} J {k g}^{- 1}$

$= - 7.3 \times 10^{- 9} J {kg}^{- 1}$
