2.) A wire has diameter 3.0 mm and carries uniform current of 15 A into the page. a.) Find a set of expressions for the magnitude of magnetic field produced by the wire as a function of
r
. You may leave these expresslons In terms of variables (10 pts). b.) A point charge carrying
1.6\times 10^(-7)C
of charge is 10 mm to the right the center of the wire and travels at a speed
6.0\times 10^(7)(m)/(s)
to the right. What is the magnitude and direction of the force it feels as a result of the wire's magnetic field? (8 pts)
