Question

obtain the expression for electric field due to an infinitely long charged wire​

Answer 1

Explanation:

Electric field due to infinite long charged wire

Since the magnitude of the electric field for the entire curved surface is constant, E is taken out of the integration and Qencl is given by Qencl = λL. The electric field due to the infinite charged wire depends on 1r rather than 1r2 for a point charge.
