Question

The distance between tow objects is increased by 3 times the original distance. How will this change the force of attraction between the two objects?

Answer 1

force of attraction will be increased by 9

Step-by-step explanation:

force of attraction is inversely proportional to square of distance

i.e F= 1/R²

F=1/3R²

F=1/9R

• multiply both side by 9

9×F= 9×1/9R

9F= 1/R

so force of attraction is 9 times
