Question

Find the magnitude of the electric field at a point 4 cm
away from a line charge of density 2 x 10- C/m.
​

Answer 1

Answer:

This answer is according to the values provided by you.

Explanation:

# 1. If there is any change in the values, you can substitute them in the above derived formula equation B.

#2. This formula is derived for electric field at the axis of the linear charged body. This is not applicable for equitorial point.

#3. Length of the body was not provided. So there is "L" variable left in the final answer. If there is any change, you can put it in the above derived formula.
