The magnitude (size) of the force,

, between two charged particles a distance

apart is given by the equation below. Ke is a constant.

Rearrange this equation to make Ke the subject.

F = Ke Q1 Q2
r2

The answer should not include any brackets and should use super/sub script where necessary.

There should be a division line between the top and bottom line of the equation to the right of the = sign and the numbers following Both Q's should be subscript.But the number 2 following the r is superscript
