Two wires with currents 2A and 1A are enclosed in a circular loop. Another wire with current 3 A is situated outside the loop as shown. The `ointveB.dvecI` around the loop is

A

`mu_(0)`

B

`3 mu_(0)`

C

`6 mu_(0)`

D

`2 mu_(0)`

Text Solution

Verified by Experts

The correct Answer is:
D
`I_("net") = 2 - 1 = 1A`
`oint vecB. Dvecl = mu_(0) I_("net") = mu_(0) xx 1 = mu_(0)`
