Two positively charged spheres of masses m1 and m2 are suspended from a point common at the ceiling by two identical insulating massless strings of length l.Charge on two spheres are q1 and q2 respectively At equilibrium both strings make the same angle theta with the vertical Then q1m1=q2m2 m1=m2 m1=m2sintheta q2m1=q1m2.

q1m1=q2m2
m1=m2
m1=m2sintheta
q2m1=q1m2.

let separation between the spheres be r and tension on each string be T.
So, Tcostheta = m1g
      Tcostheta = m2g
 => m1=m2
