In the given figure the magnitude of magnetic field at `O` is ( all three wires are quarter circular ares )

A

`(mu_(0)I)/(4R)sqrt(3)`

B

`(mu_(0)I)/(2R)sqrt(3)`

C

`(mu_(0)I)/(8R)sqrt(3)`

D

`(mu_(0)I)/(6R)sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
c
`B=(mu_(0)I)/(4pir)((pi)/(2)),B` due to all three arc will be mutually perpendicular `B_(n et)=sqrt(3)(mu_(0)I)/(8R)`
