Equipotential surfaces are always at right angles to the electric field. TRUE of FALSE?
Homework Answers
The electric field points from high potential region to low potential region. all the points on an imaginary surface perpendicular to the electric fdield lines have the same potential. The potential only changes in the direction of the electric field or in the opposite direction of the electric field. the potential is same in perpendicular direction to the electric field. therefore, the any imaginary surafce perpendicular to the electric field has same potential any point on it.
The statement is TRUE.
