Question

please just do part b. thanks.

1. Point Charge and Solenoid (a) A point charge q is located at a position (r, y, z) = (d,0,0). An infinite solenoid with n turns/length, radius R, (d > R), and carrying steady current I is positioned along the z-axis. Find the linear momentum and angular momentum (about the origin) in the fields. (b) Now consider the same situation as in part (a), but take the current to have a time-dependence I = 0, <0, I = 100 SEST, I = 1o, t > T, where T is a given time. For 0 <t<T, determine the linear momentum and angular momentum (about the origin) in the fields.
