# Velocity of a charge moving in a magnetic field

The problem states:

A particle with a charge of -5.90 * 10^-9 C is moving in a uniform magnetic field B(vector) = -(1.25 T) k (hat). The magnetic force on the particle is measured to be F(vector) = -(4.00 * 10^-7 N) i(hat) + (7.60 * 10^-7 N) j(hat).

1. Are there components of the velocity that are not determined by the measurement of the force?

Yes or No

2. Calculate the x-component of the velocity of the particle.

3. Calculate the y-component of the velocity of the particle.

4. Calculate the scalar product v(vector) * F(vector.

5. What is the angle between v(vector) and F(vector)? Give your answers in degrees.

velocity of a charge moving in a magnetic field

Hello,

I'm having difficulty understanding the whole vector notation thing and how to compute forces or velocities accordingly. Honestly, I need major help (this is the second time i take the course after failing the first time) so if anyone out ther can help 100% i'm willing to increase the bids..

Thank you.
