Q. A particle with a charge of q = -5.40 nC is moving in a uniform magnetic field of vec{B}=( -1.24 T ) hat{z}. The magnetic force on the particle is measured to be vec{F}= ( -7.60×10-7 N )hat{y}. Calculate v_x, the x component of the velocity of the particle.
Q. pilot flies her route in two straight-line segments. The displacement vector A for the first segment has a magnitude of 231 km and a direction 30.0o north of east. The displacement vector for the second segment has a magnitude of 172 km and a direction due west. The resultant displacement vector is R = A + B and makes an angle θ with the direction due east. Using the component method, find (a) the magnitude of R and (b) the directional angle θ.
