Homework Answers
Given,
The change in electric potential energy, U2 - U1 = 7 * 10-22 J
The dipole moment, p = 6.2 * 10-30 Cm
where, U1 is the potential energy perpendicular to E
U2 is the potential energy aligned with the field
We know,
U2 - U1 = p * E
7 * 10-22 =6.2 * 10-30 * E
E = 1.129 * 108 N/C
