What is true about the electric field and electric force?
Correct answer: C. Electric field lines are towards the negative and electrons flow in the opposite direction.
- A. Electric field lines are towards negative and electron flow in same direction
- B. Electric field lines are towards positive and electron flow in opposite direction
- C. Electric field lines are towards the negative and electrons flow in the opposite direction.
- D. Electric field lines are positive and electrons flow in the same direction.
Explanation
Electric field lines always point away from a positive charge and towards a negative point. In fact, electric fields originate at a positive charge and terminate at a negative charge.This shows that OPTION B and D ARE INCORRECT. Electrons flow from lower potential terminal to higher potential terminal being negatively charged particles it flows from negative to positive poles hence it is the opposite direction as the electric field.So,OPTION C is incorrect.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
