Question

Gravitational mass is proportional to the gravitational _______

• A. temperature
• B. charge
• C. gravitational force
• D. area

Answer 1

The correct option is C gravitational force

Inertial mass is given by $m=\frac{F}{a}$
Gravitational mass is given by $m=\frac{F_g{R}^2}{GM}$
where $F_g$ is the gravitational force, $R$ is distance between two masses $M$ and $m$.
Inertial mass is free from gravitational force. It depends upon only mass. Gravitational mass is dependent on gravitational force.
