If two magnets exerta a repulsive force of 100 newtons when they are 40 cm apart What will the force be when they are 8 cm apart?

From : R.Dharmendran (9650817206)

FORCE IS INDIRECTLY PROPORTIONAL TO THE SQUARE OF THE DISTANCEW BETWEEN THEM.. SO THE FORCE WILL BE STRONGER WHEN GOES NEARER.

SO THE VALUE IS 2500N WHEN IT IS 8cm apart
