Which formula do you use for this problem ?
two charged spheres, one suspended from a insulated thread and another held in place and unable to move.

when one sphere S1 is brought to a distance of 2.00 x 10^-2m from S2, the acceleration of S1 is 3.00 x 10^10 m/s^2. If S1 is brought to a distance of 4.00 x 12^-2 from S2, then the magnitude of the acceleration of S1 will be ???
What formula do I use???
