question 10

Multiple Choice

A long straight wire on the z-axis carries a current of 6.0 A in the positive direction.A circular loop in the xy-plane,of radius 10 cm,carries a 1.0-A current,as shown in the figure.Point P,at the center of the loop,is 25 cm from the z-axis.An electron is projected from P with a velocity of 1.0 × 10⁶ m/s in the negative x-direction.What is the y component of the force on the electron? (e = 1.60 × 10^-19 C,μ₀ = 4π × 10^-7 T ∙ m/A)
