In the given figure two semicircular wires are connected which are in and plane respectively. And `+2 q_(0)` charge is distributed uniformly over it. The magnitude of electric field intensity at the origin is `(q_(0))/(2^(n//2) pi^(2)epsi_(0) R^(2))` find n.

Text Solution

Verified by Experts

The correct Answer is:
A
`E_y=(q_0)/ (2 pi r^2 e_0 R^2), E_(net) = sqrt (E y^2+ E_2^2)= (q _0)/(sqrt2 pi^2 e_0 R^2)`
