Two objects of equal masses placed at a certain distance from each other attract each other with a force F. If one-third of the mass of one object is transferred to the other object, then the new force will be

Asked in JEE Main 28th June 2nd Shift 2022 · Force between two masses

Answer: (3) 8/9F

Step-by-step solution

Start with masses m and m a distance d apart, so F=(Gm²)/(d²).

Transferring m/3 leaves (2m)/3 on one object and puts (4m)/3 on the other, and the distance does not change.

The new product of masses is (2m)/3×(4m)/3=(8m²)/9.

So the new force is 8/9F.

Why the other options are wrong
