An electron goes from one equipotential surface to another along one of the four paths shown below. Rank the paths according to the absolute value of work done by the electric field, from least to greatest.

An RLC series circuit has L = 100 mH and C = 1.00 μF. It is connected to a 1000-Hz source and the source emf is found to lead the current by 75.0◦. The value of R is:
