Question 14

The gravitational force between two point-mass objects P P\,P and Q Q\,Q is F1F_1F1​. The mass of P P\,P decreases (remaining greater than zero) and the distance between P P\,P and Q Q\,Q is doubled. Which statement about the new gravitational force F2 F_2\,F2​ between these two objects is correct?

A

F2>0.25F1F_2 > 0.25F_1F2​>0.25F1​

B

F2=0.25F1F_2 = 0.25F_1F2​=0.25F1​

C

0<F2<0.25F10 < F_2 < 0.25F_10<F2​<0.25F1​

D

0.25F1<F2<F10.25F_1 < F_2 < F_10.25F1​<F2​<F1​
