A dipole has dipole moment p = 1.5 x 10-⁹ C m oriented in the +x direction and is in a uniform electric field of strength Eo = 4.0 × 106 N/C that is directed 30° from the dipole as shown. The axis perpendicular to the dipole and a test point on that axis are also shown. Eo * (a) What would the charge separation in this dipole be if it were due to one electron and one proton (ie a hydrogen atom)? What would the separation be if it were due to charges of ±1nC? (b) Find the magnitude of the torque on the dipole. (c) Find the work required to rotate the dipole until it is antiparallel to the field (i.e., until p' points in the opposite direction of the electric field). (d) What would be the torque on the dipole if the dipole were oriented antiparallel to the field?

The electric dipole in the figure consists of two charges, +Q and -Q, that are a distance, d, apart, where Q = 65.4 nC and d = 39.3 cm. Point A, which lies along the vertical (dotted) line midway between the two dipole charges, is an unknown distance, r, from the +Q charge. SYMBOLIC INPUT. Use the variables from the problem: Q, d, r, and Coulomb's constant, k, as needed. Electric Potential (1 of 2) The electric potential at point A will be zero The electric potential at point B will be zero zero zero This tells you that the electric field is perpendicular to perpendicular to the middle line..
