An electric dipole is put in north-south direction in a sphere filled with water. Which statement is correct
A charge $q$ is placed at the center of one of the surface of a cube. The flux linked with the cube is :-
$(a)$ An electrostatic field line is a continuous curve. That is, a field line cannot have sudden breaks. Why not?
$(b)$ Explain why two field lines never cross each other at any point?
