Magnetic Force on a Moving Charge

[GodxIsInTheTV]

Homework Statement

A magnet produces a 0.5 T field between its poles, directed to the east. A dust particle with charge q = -8 times 10-18 C is moving straight down at 0.6 cm/s in this field. What is the magnitude and direction of the magnetic force on the dust particle?

Homework Equations

F= qv X b

The Attempt at a Solution

Tried converting .6 cm/s into m/s and solving since the sin (90) would still be 1, but it keeps telling me I am wrong.

Hi, you need to be more explicit as to what you have tried which you said did not correspond to the correct answer. What is your answer? It's a vector isn't it?
