You can use q = 2.0 C and d = 1. (f) Look at the figure below. Imagine the dipole rotates from orientation (1) to orientation (2).

You can use q = 2.0 C and d = 1.5 nm. (f) Look at the figure below. Imagine the dipole rotates from orientation (1) to orientation (2). Is the work done by the electric field positive, negative, or zero? (g) If instead, the dipole rotates from orientation (1) to orientation (4), is the work done on the dipole by the field more than, less than, or the same as in (f)?
