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.

If i1 is greater than i2, then the force on q is north.
If i1 = - i2, then the wires repel each other.
If v = 0, then the force on q is zero.
If i2 = 0 and i1 is greater than zero, then the magnetic field near charge q points out of the page.
If i1 = 0 and i2 is greater than zero, then the force on q points out of the page.
If i2 = - i1 then the force on q equals zero.
If i2 = 0 and i1 is greater than zero, then the force on q is north.

Explanation / Answer

True, because F= q V xB

True, same concept here also F= q V xB

True, V becomes zero, so force is zero

False, it points into the page

False, force is southwards

False, force is northwards

True, because F= q V xB
