agnetic field at the position of the dot in the following fi

agnetic field at the position of the dot in the following figure (Figure 1) ? Give your answer as a vector.

Express your answer in terms of the unit vectors i^, j^, and k^. Use the \'unit vector\' button to denote unit vectors in your answer.

Solution

B = [mu₀ q / 4 pi] [v_y / r³]

r³ = (0.01² + 0.01²)^3/2 = 2.83 * 10^-6 m

B = ( 4 pi * 10^-7 * 1.6 * 10^-19 / 4 pi) [2 * 10⁷ / (2.83 * 10^-6)³]

= 1.13 * 10^-15 T
