Question

1. If the distance between two bodies that attract each other is
trebled, how many times more will be their mutual force of
attraction?
a. 9 times
b. 3 times
c. 1/3
d. 1/9​

Answer 1

Answer:

Option d

Explanation:

Force of attraction between 2 bodies is inversely proportional to square of distance between 2 bodies

F Proportional to 1/d

As radius is tripled , the force will be divided by (3)²

i.e. 1/(3)² times = 1/9 times the force
