Two equal charges exert equal forces on each other. what if one charge has twice the magnitude of the other?
1. the bigger charge will exert a force four times as strong.
2. the smaller charge will exert a force four times as strong.
3. the smaller charge will exert a force twice as strong.
4. the bigger charge will exert a force twice as strong.
5. the forces will be equal.

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp, max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
