A 1.20T magnetic field points northeast. Part A Find the magnitude of the force

Question

A 1.20T magnetic field points northeast.

Part A

Find the magnitude of the force on a +0.55Ccharge that is moving 11m/s toward the north.

Part B

Find the direction of the force on a +0.55Ccharge that is moving 11m/s toward the north.

Part C

Find the magnitude of the force on a +0.55Ccharge that is moving 11m/s toward the east.

Part D

Find the direction of the force on a +0.55Ccharge that is moving 11m/s toward the east.

Part E

Find the magnitude of the force on a +0.55Ccharge that is moving 11m/s toward the south.

Part F

Find the direction of the force on a +0.55Ccharge that is moving 11m/s toward the south.

Part G

Find the magnitude of the force on a +0.55Ccharge that is moving 11m/s toward the west.

Part H

Find the direction of the force on a +0.55Ccharge that is moving 11m/s toward the west. (up or down?)

Part I

Find the magnitude of the force on a +0.55Ccharge that is moving 11m/s toward the southwest.

*on the direction of the force questions is either up or down

Explanation / Answer

Part A)

F = qvBsin(angle)

F = (.55)(11)(1.2)(sin 45)

F = 5.13 N

Part B)

By the right hand rule, the force is down

Part C)

F = (.55)(11)(1.2)(sin 45)

F = 5.13 N (same as part A)

Part D)

By the right hand rule, the force is up

Part E)

F = (.55)(11)(1.2)(sin 45)

F = 5.13 N

Part F)

By the right hand rule, the force is up

Part G)

F = (.55)(11)(1.2)(sin 45)

F = 5.13 N

Part H)

By the right hand rule, the force is down

Part G)

The force is zero N since the B field is parallel to the direction of velocity
