Figure shows three points A,B and C in a region of uniform electric field E. The line AB is perpendicular and BC is parallel to the field lines. Then which of the following holds good. Where CA, VB and VC represent the electric potential at points A,B and C respectively.
Correct answer: C. VA=VB>VC
- A. VA=VB=VC
- B. VA=VB<VC
- C. VA=VB>VC
- D. VA>VB=VC
Explanation
The correct option is c) VA=VB>VC. In a region of uniform electric field E, the electric potential at point A and point B will be equal and higher than the potential at point C. The electric potential decreases in the direction of the electric field, with point C having the lowest potential as it is parallel to the field lines.

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.
