A In question 3, If the dipole rotates from orientation 1 to orientation 2, is the work done on the dipole by field positive, negative, or zero ?
B If, instead, the dipole rotates from the orientation 1 to orientation 4, is the work done by the field more than, less than, the same as in (a) ?

Text Solution

Verified by Experts

a. Electric field will do positive work, if dipole rotates such that its angle decreses with E.
b. 2 and 4 orientations are identical. Hence, work done will be same.
