Suppose the charge of a proton and an electron differ slightly. One of them is -e, the other is (e+Δe). 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 Δe is of the order of [Given mass of hydrogen mh=1.67×10−27Kg]

ANSWER
Given : mh=1.67×10−27 kg
Net charge on hydrogen atom q=(e+Δe)−e=Δe
Let the distance between them be d.
Equating gravitational force and the electrostatic force, we get
d2Gmh2=d2k(Δe)2
Or d2(6.67×10−11)
