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 i10 and i2 is greater than zero, then the force on q points out of the page. If i2-0 and i1 is greater than zero, then the force on q is north. i andnth greater than zero, then the force on q is north. If i2- i1 then the force on q equals zero. If i1 is greater than i2, then the force on q is north. If i1i2, then the wires are attracted to each other If 10 and i2 is greater than zero, then the magnetic field near charge q points into the page Submit Answer Tries 0/10

Explanation / Answer

(a)

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

FALSE

(b)

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

TRUE (F = qvB. if v = 0, F = 0)

(c)

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

TRUE (from left hand rule, force is in north)

(d)

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

FALSE (force is not 0)

(e)

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

TRUE (net magnetic field is into the page. so, the force on q is north.)

(f)

If i1 = i2, then the wires are attracted to each other.

TRUE

(g)

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

FALSE (magnetic field to be pointing out of the page.)
