MCQ
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

  • A
    Statement $1$ is true, Statement $2$ is true,
    Statement $2$ is the correct explanation of Statement $1$ 
  • B
    Statement $1$ is true, Statement $2$ is true,
    Statement $2$ is not the correct explanation of Statement $1$

  • D
    Statement $1$ is false, Statement $2$ is true

Answer

Correct option: C.
Statement $1$ is true, Statement $2$ is false
c
The work done is moving a charge along an equipotential surface is always zero. The directIon of electricfield is perpendicular to the equipotential surface or lines
