Calculate the distance between two charges of 4C forming a dipole, with a dipole moment of 6 units
b Explanation: The dipole moment is given by, M = Q x d. To get d, we rearrange the formula d = M/Q = 6/4 = 1.5units
b Explanation: The dipole moment is given by, M = Q x d. To get d, we rearrange the
See lessformula d = M/Q = 6/4 = 1.5units
