A particle with charge -5 nC is moving in a uniform magnetic field B = -(1.2 T)k. The magnetic force on the particle is measured to be F = -(3.6*10^(-7) N)i + (7.6*10^-7)j. Calculate the x and y components of the particle's velocity.(adsbygoogle = window.adsbygoogle || []).push({});

F = q(V X B)

(force equals charge multiplied by the cross product of V and B)

Calculate the scalar product (dot product) v*F

vx*Fx + vy*Fy + vz*Fz?

What is the angle between v and F (in degrees)?

F = qvB sin theta

theta = arcsin [F/(qvB)]?
