NEET Physics Question - Gravitation - Gravitational Potential

Two masses of 10²kg and 10³ kg are separated by 1 m distance. Find the gravitational potential at the mid point of the line joining them.

-2200 G

-1100 G

-2500 G

-100 G

Gravitational potential \( V \) at the midpoint is the sum of the potentials due to both masses:

\[
V = -\frac{G \cdot 10^2}{0.5} - \frac{G \cdot 10^3}{0.5}
\]

Simplifying:

\[
V = -2G(10^2 + 10^3) = -2G \cdot 1100
\]

So, the gravitational potential at the midpoint is:

\[
V = -2200G
\]
