![Suppose a radio signal has a 3 [N/C] E-field, pointing downward at time t=0. If the tip of an old-fashioned "whip"
antenna is 7 mm diameter, how much charge would be spread over that antenna tip? (antenna is a good metal
conductor, so the E-field inside it is zero)
{start-out: should they be positive, or negative?}
{follow-up: where did they come from? what charge is there, now?}
