A charge of `10^(-6)C` is describing a circular path of radius 1cm making 5 revolution per second. The magnetic induction field at the centre of the circle is

A

`pixx10^(-10)T`

B

`pixx10^(-9)T`

C

`pi/2xx10^(-10)T`

D

`pi/2xx10^(-9) T`

Text Solution

Verified by Experts

The correct Answer is:
A
`B=(mu_(0)qomega)/(4pir) =(4pixx10^(-7) xx10^(-6)xx5xx2pi)/(4pixx1xx10^(-2)) =pi xx 10^(-10)T`
