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 False If i1 = 0 and i2 is greater than zero, then the magnetic field near charge q points into the page.
True False If i1 = 0 and i2 is greater than zero then the force on q is south.
True False If i1 = 0 and i2 is greater than zero, then the force on q points out of the page.
True False If i1 is greater than i2, then the force on q is north.
True False If i1 = i2, then the wires are attracted to each other.
True False If i2 = - i1 then the force on q equals zero.
True False If v = 0, then the force on q is zero.
True False If i1 = 0 and i2 is greater than zero, then the magnetic field near charge q points into the page.
True False If i1 = 0 and i2 is greater than zero then the force on q is south.
True False If i1 = 0 and i2 is greater than zero, then the force on q points out of the page.
True False If i1 is greater than i2, then the force on q is north.
True False If i1 = i2, then the wires are attracted to each other.
True False If i2 = - i1 then the force on q equals zero.
True False If v = 0, then the force on q is zero.
Explanation / Answer
1)
If i1 = 0 and i2 is greater than zero, then the magnetic field near charge q points into the page. - False (it points to bottom of page)
2)

4)
If i1 is greater than i2, then the force on q is north. False
5)
If i1 = i2, then the wires are attracted to each other.False
6)
If i2 = - i1 then the force on q equals zero.True
7)
If v = 0, then the force on q is zero.True
