$0.96m$

$a.$ as two like charges are present in this case,they will try to push the apart from each other.

$b.$ we know electrostatic force acting $F$ due to two like charges of $q$ separated at a distance of $r$ is given as,

$F= 1/(4 pi epsilon) (q*q)/(r^2)$

Given, $F=0.66,1/(4 pi epsilon)=9*10^9,q=8.4*10^-6$

so,putting the provided value we get,

$r=0.96 m$

Two point charges with charges of 8.4xx10^-68.4xx10^-6 are brought close to each other. (a). Sketch this and show the direction of the electric force? (b) If the point charge on the left feels a force of 0.66N,0.66N, calculate the distance, r,r, between them?
