It means you put Gravitational force=Electrostatic force so
G100x100/R^2=qxq/R^2 assuming vacuum medium
so q^2=10^4G
or q=100sqrt(G) C Take G from the tables an d compute q.
lvan, you forgot the coulomb constant (k):
F= G*(100^2)/(r^2) = k*(q^2)/(r^2)
q = 100*sqrt(G/k)
k = (c^2)*10^(-7)
where c = speed of light = 299792458m/s
G = 6.674*10^(-11)
approximately
