PHY 102 ELECTROSTATICS Objective Question
Take CBT

Question

What is a key characteristic of electric field lines at the surface of a conductor in electrostatic equilibrium?
Options
A They are parallel to the surface of the conductor.
B They are perpendicular to the surface of the conductor.
Correct Answer
C They are absent inside the conductor.
D They always curve towards sharp edges.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document explains, 'As such, field lines are perpendicular to the surface of conductors.' (page 18, 'Arrangement of Charges on a Conductor' section). It also mentions that electrons would move if there were a parallel component, negating equilibrium.

Hint

Think about what would happen if field lines weren't perpendicular at the surface of a conductor in equilibrium.
