Two long straight wires are connected by a circular section which has a radius `R`. All the three segments lie in the same plane and carry a current `I`. The magnetic induction at the centre `O` of the circular segments is

A

`(mu_(0)I)/(4piR)`

B

`(alphamu_(0)I)/(4piR)`

C

`(alphamu_(0)I)/(R)`

D

`(alphamu_(0)I)/(2piR)`

Text Solution

Verified by Experts

The correct Answer is:
2
