NEET Physics Electric Field MCQ Question
Consider a diagram showing an infinitely long straight uniformly charged wire. Which of the following correctly describes the electric field pattern around this wire?
The electric field lines are radial and perpendicular to the wire.
The electric field lines form concentric circles around the wire.
The electric field lines are parallel to the length of the wire.
The electric field lines are directed inwards towards the wire.
Correct Answer
Detailed Explanation
For an infinitely long straight uniformly charged wire, Gauss's law indicates that the electric field lines are radial and perpendicular to the wire. This is due to the cylindrical symmetry of the charge distribution.
