How much work is done to move a point charge (q) a
distance of x, at an angle of 30° to the lines of force of an
electric field (E)
A. qEx
B. qEx sin(30°)
C. qEx cos(30°)
·D. Zero
None of the answer choices seem to be right? The answer says it's b which can't be true.
Work = Force x Displacement. The displacement here is xcos30. Force = Eq. Therefore, the answer should be C ??
