Two charges Q1 amd Q2 jabe a force of 3.1x10^-8 N when the distance between them is 3m. Use the formula F = kQq/R2 to determine the force when the distance (R) between charge Q1 and Q2 increased from 3m to 4.5m
My attempt was that
F = 1/R^2
k= 9.0x10^9
F=(3/4.5)^2
F=0.44N
3.1x10^-8 / 0.44
=.7 x10^-8
The answer being F = .7 x10^-8 N
Is that correct?
