The variation of electric potential due to a point charge with distance is represented by the graph (where V along y-axis and r along x-axis)
Correct answer: D. D
- A. A
- B. B
- C. C
- D. D
Explanation
The electric potential due to a point charge is V=kQ/r. Where r is the distance between the charges and Q is the magnitude of the charge. K is Coulombs constant who's value is 9x I09Nm2/C2.As, V ∝ 1/r so the graph will be rectangular hyperbola.

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.
