- AElectric lines of force never cross each other.
- BElectric lines of force end at a positive.
- CThe electric field charge inside a conductor are infinity.
- DLines of electric field point towards regions of lower potential.
Explanation:
If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location. This could never be the case. Therefore the lines representing the field cannot cross each other at any given location.
Electric field end at a negative charge.
Along the electric field line potential drops.
