Question

Let $V_G$ and $E_G$ denote gravitational potential and gravitational field respectively, then choose the wrong statement.

• A. $V_G=0,E_G=0$
• B. $V_G\ne 0,E_G=0$
• C. $V_G=0,E_G\ne 0$
• D. $V_G\ne 0,E_G\ne 0$

Answer 1

The correct option is C $V_G=0,E_G\ne 0$

Gravitational field can be zero when the masses are placed such that the field due to each other cancel out or if all the masses are zero.
Gravitational potential is zero, only when the masses are zero. Hence, it is not possible to have a non zero field with zero potential.
