Answer:

Correct Answer: 12. (c)

Solution:

Since, $f = G \frac{M_{1} M_{2}}{d^{2}}$ therefore the affecting factor are:

(i) Mass of the two bodies i.e., $f \propto M_{1} M_{2}$ When mass increases gravitational force increase.

(ii) The distance between thier centers; i.e., $f α$ $\frac{1}{d^{2}}$ when the distance increases gravitational force decreases.
