Suppose the charge of a proton and an electron differ slightly. One of them is -e, the other is (e + \(\Delta\) e). If the net of electrostatic force and the gravitational force between two hydrogen atoms placed at a distance d (much greater than atomic size) apart is zero, then \(\Delta\) e is of the order of [Given mass of hydrogen = 1.67 \(\times\) 10-27 kg]
