) Two particles, each of mass m and carrying charge Q, are separated by some distance.If they are in equilibrium under mutual gravitational and electrostatic forces,then Q/m (in C/Kg) is of the order of(a) 10-5(b) 10-10(c) 10-15(c) 10-20

Assuming the charges are aligned vertically one after another as gravity force is also acting upon them.
Therfore, Balancing the elctrostatic force with mg force,
KQ^2/r = 2mg
Q^2/m = 2gr/K
{order == 10^-8}
which is near 10-10.
