If `B` is the magnetic induction, at the centre of a circular coil of radius `'r'` carrying a current is `1T`, then its value at a distance of `sqrt(3)r` on the axis from the centre of the coil is

Options

A. `(1)/(8)T`
B. `(1)/(16)T`
C. `8T`
D. `(1)/(4)T`

Answer

1

Explanation

`(B_(a))/(B_(c))=(R^(3))/((x^(2)+R^(2))^(3//2))`
