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. (It is midway between the two wires, as shown) ("North" is up the page, "East" is right, and so on.)

For the statements below, select T-True, F-False. If the first is T and the rest F, enter TFFFF.

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

ANSWER IS NOT TTTFFT

Please have an explanation, it would be really helpful.

Explanation / Answer

Direction of Magnetic field due to current carrying wire at a point can be determined by pointing thumb of right hand tiwards current direction and point the palm such that it points towards point under consideration.The dircetion in which the palm curls is the direction of magnetic field.This fact is used to answer all the questions below:

A) True

B)False

C)True

D)False

E)False

F)True
