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.

True or False:

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

Explanation / Answer

If v = 0, then the force on q is zero.= True

If i1 = 0 and i2 is greater than zero, then the magnetic field near charge q points into the page. = False

If i1 is greater than i2, then the force on q is north.= True

If i1 = 0 and i2 is greater than zero then the force on q is south.= True

If i1 = - i2, then the wires repel each other.= False

If i1 = 0 and i2 is greater than zero, then the force on q points out of the page.= False

If i2 = - i1 then the force on q equals zero.= false
