I need some help:

A long, rigid conductor, lying along an x axis, carries a current of 3.81 A in the negative x direction. A magnetic field B is present, given by B = 2.10 i + 8.62 x²j, with x in meters and B in milliteslas. Find (a) the x-component, (b) the y-component, and (c) the z-component of the force on the 1.68 m segment of the conductor that lies between x = 1.46 m and x = 3.14 m.
