A current of 1.0 ampere is flowing in the sides of an equilateral triangle of side `4.5 xx 10^(-2)` m. Find the magnetic field at the centroid of the triangle. (Permeability constant `mu_(0) = 4pi xx 10^(-7) V-s//A-m`)

Options

A. `4.0 xx 10^(-5) "weber"//m^(2)`
B. `6.0 xx 10^(-8) "weber"//m^(2)`
C. `2.0 xx 10^(-5) "weber"//m^(2)`
D. `7.0 xx 10^(-12) "weber"//m^(2)`
