Question

An infinite line charge produces a field of 9 × 10⁴ N/C at a distance of 2 cm. Calculate the linear charge density.

Answer 1

Step 1: Electric field due to infinite line charge

Electric field due to infinite line charge is given by:

Where λ is the linear charge density and d is the perpendicular distance of point from the infinite line charge.

Step 2: Substituting the values
