NEETPhysicsElectrostaticsMCQ+4 / −1

The angle between the electric lines of force and the equipotential surface is

  1. A
    0∘^\circ∘
  2. B
    45∘^\circ∘
  3. C
    90∘^\circ∘
  4. D
    180∘^\circ∘

Correct answer: C

dV = $-$$\overrightarrow E $ . d$\overrightarrow r $

dV = $-$Edr cos$\theta$

For equipotential surface,

dV = 0

cos$\theta$ = 0

$\Rightarrow$ $\theta$ = 90$^\circ$
