Question

Each of two small spheres is charged positively, the total charge being 52.6 wC. Each sphere is repelled from the other with a force of 1.19 N when the spheres are 1.94 m apart. Calculate the charge on each sphere. 

Answer 1

$F=\frac{kq^2}{r^2},\implies$

$q=r\sqrt{\frac Fk}=22.3~\mu C.$
