If the strength of the magnetic field produced 10cm away from a infinitely long straight conductor is `10^(-5)"Weber"//m^(2)` , the value of the current flowing in the conductor will be

Options

A. 5 ampere
B. 10 ampere
C. 500 ampere
D. 1000 ampere

Answer

C

Explanation

`B = (mu_(0) I)/(2pi r) implies 10^(-5) = (10^(-7) xx 2 xx I)/(0.1)`
`implies I = (10^(-6))/(2 xx 10^(-7)) = 5 A `
