Question

In the picture below, the two wires carry current i1 and i2, respectively, with positive current to the right. The charge q is positive and has velocity v to the right.

Select True or False for all of the following   
A.) If i1 = - i2, then the wires repel each other.
B.) If i2 = - i1 then the force on q equals zero.
C.) If i1 = 0 and i2 is greater than zero, then the magnetic field near charge q points into the page.
D.) If i2 = 0 and i1 is greater than zero, then the force on q points into the page.
E.) If v = 0, then the force on q is zero.
F.) If i1 is less than i2, then the force on q is south..
G.) If i2 = 0 and i1 is greater than zero, then the force on q is north.
