What does it mean when equipotential lines are closer together?
According to the diagram the arrowed lines are equipotential lines.
Out of the given statements which of the following are true :
A) Work done in moving a charge on equipotential surface is zero.
B) Electric lines of force are always normal to equipotential surface.
C) When two like charges are brought closer, the electrostatic potential energy of the system is decreased.
D) Electric lines of force converge at positive charge and diverge at negative charge.
positive ions are surrounded and are held together in a sea of delocalised electrons.
