A circular wire loop of radius, carries a total charge of, distributed uniformly over its length. A small length of, of wire is cut off. The magnitude of the electric field at the centre due to the remaining wire is,
(Assume SI units)
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Let's divide the loop in two parts. 1. The small element of length, dl, which is to be cut off, 2. The Remaining part of the loop, Initially, by symmetry, the net Electric field at the center is zero. ∴ E Remaining Wire +Edl element =0, ⇒E remaining…
