Question

In which direction does the electric field point at a position directly south of a positive charge?

A. West
B. North
C. East
D. South

Answer 1

B. north

The electric field at a position directly south of a positive charge points radially outward from the charge. In other words, it points away from the positive charge in all directions, including towards the north, east, west, and upward. So, if you are standing directly south of a positive charge, the electric field will point away from you, opposite to the direction you are facing, in this case North

Answer 2

The electric field at a position directly south of a positive charge points radially outwards from the charge. This is because when we say the position is directly south of the positive charge, it means that the position lies in a straight line below the charge.
