PhysicsElectric Charges and FieldsMHT CET

Suppose the charge of a proton and an electron differ slightly. One of them is and the other is . If the net of electrostatic force and gravitational force between two hydrogen atoms placed at a distance d (much greater than atomic size) apart is zero, then is of the order (Take, mass of hydrogen, kg)

Answer: (C)

Solution

Net charge of an atom is , so e)^2d^2Gm_h^2d^2m_h$ =
