From an infinite stright conductor carrying a current of 100 A, the magnetic field at a distance 5m

A

4 T

B

`4xx10^(-6)T`

C

`3.8xx10^(-6)T`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Magnetic field `B=(mu_(0))/(4pi)*(2I)/(a)`
`=(10^(-7)xx2xx100)/(5)=4xx10^(-6)T`
