What is not true for equipotential surface for uniform electric field?
1 Equipotential surface is flat
2 Two equipotential surfaces can cross each other
3 Electric lines are perpendicular to equipotential surface
4 Work done is zero
Explanation:
Equipotential surface for uniform electric field is perpendicular planes to the field as shown
Option (2) is not true as two equipotential surface cannot cross each other.

The angle between the electric lines of force and the equipotential surface is
1 \(45^\circ \)
2 \(90^\circ \)
3 \(180^\circ \)
4 \(0^\circ \)
Explanation:
Electric field is always perpendicular to equipotential surface.

Assertion : Electric field is always directed perpendicular to an equipotential surface. Reason : Equipotential surface is a surface on which at each point potential is same.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
\(E=\dfrac{\Delta V}{\Delta r}(\) or \() \Delta V=\vec{E} \cdot \overrightarrow{\Delta r}\) \(\Delta V=E(\Delta r) \cos \theta\) For \((E P S), \Delta V=0 \Rightarrow \theta=90^{\circ}\). An equipotential surface \((E P S)\) is defined as a surface where the electric potential is constant at every point. The electric field lines are always perpendicular to equipotential surfaces. This is because if there were an electric field component parallel to the surface, there would be a potential difference along the surface, which would violate the definition of an equipotential surface. So correct option is (1).
