An object of charge q1 = -3.2 C is traveling in the +x x^ direction with a speed

Question

An object of charge q1 = -3.2 C is traveling in the +x x^ direction with a speed of v= 3 m/s in a region of magnetic field B B= -5.3 T y y^.

In what direction is the force on q1 due to the magnetic field?

Arrow A

Into the page

Out of the page

Arrow B

Arrow C

Arrow D

Arrow E

Arrow F

Arrow G

In the direction of v v

In the opposite direction of v v

2)

What is the magnitude of the force due to the magnetic field on the object?

F = 36 N

F = 17 N

F = 0 N

F = 50.9 N

3)

An object of charge q2=+2.3 C is traveling in the (x+y)/2(x+y)/2 direction with an unknown speed of v in a region of magnetic field B B = -6.3 T z z^ (the field points into the page). The object q2 feels a magnetic force of magnitude 7.14 N.

In what direction is the force on q2 due to the magnetic field?

Arrow A

Into the page

Out of the page

Arrow B

Arrow C

Arrow D

Arrow E

Arrow F

Arrow G

In the direction of v

In the opposite direction of v

Explanation / Answer

1) According to Maxwell right hand rule,

Direction of force will be into the page but since it is negative charge, final direction will be out of the page. (ans)

2) F = qVB = 3.2*3*5.3 = 50.9 N (ans)

3)  

According to Maxwell right hand rule,

Direction of force will be towards the arrow F. (ans)
