Question

The potential at the surface of a planet of mass M and radius R is assumed to be zero. Choose the most appropriate option

• A. The potential at infinity is $\frac{GM}{R}$
• B. The potential at the center of planet is $-\frac{GM}{R}$
• C. Both (a) and (b) are correct
• D. Both (a) and (b) are wrong

Answer 1

The correct option is C

Both (a) and (b) are correct

At all places potential will increase by $\frac{GM}{R}$
