Explanation Draw the labelled diagram as shown below. Write the expression for the magnetic field at a point due to a moving charge as. B → = μ 0 4 π q ( v ) ( sin θ ) r 2 (I) Here, B is the magnetic field, q is the charge, v is the velocity of charge, θ is the angle between v , and r and r is the distance of point B from charge. Write the expression for sin θ refer to the labeled figure as. sin θ = A B A C (II) Here, A B and A C are the sides of the triangle. Conclusion: Substitute 4.00 m for A B and 5.00 m for A C in equation (II). sin θ = 4.00 m 5.00 m = 4 5 Substitute 5.00 m for r , 4 5 for sin θ , 1
