Electric Potential & Equipotentials
This question has Statement-1 and Statement-2. Of the four choices given after the Statements, choose the one that best describes the two Statements.
Statement 1: No work is required to be done to move a test charge between any two points on an equipotential surface.
Statement 2: Electric lines of force at the equipotential surfaces are mutually perpendicular to each other.
Show answer and solution
Answer: (a)
- Statement 1: between points on an equipotential, so . True.
- Statement 2: field lines and equipotential surfaces are perpendicular to each other. True.
- Force is normal to the displacement along the surface, so no work: Statement 2 explains Statement 1.
- So the answer is (a).
