Question
An electron and a proton are placed 10 mm apart, the dipole moment of the system of charges is
Solution
The dipole moment (p) of a system of charges is given by the product of the charge (q) and the distance (d) between the charges.
For an electron and a proton, the charge is the same in magnitude but opposite in sign. The charge of an electron (or proton) is approximately 1.6 x 10^-19 Coulombs. The distance between the charges is given as 10 mm, which is 10 x 10^-3 meters (or 0.01 meters).
So, the dipole moment can be calculated as:
p = q * d p = (1.6 x 10^-19 C) * (0.01 m) p = 1.6 x 10^-21 C.m
So, the dipole moment of the system of charges (electron and proton) is 1.6 x 10^-21 C.m.
