A charged particle of mass m 7.6X10-8 kg, moving with constant velocity in the y-direction enters a region containing a constant magnetic field B= 1.9T aligned with the positive z-axis as shown. The particle enters the region at (x,y) = (0.51 m, 0) and leaves the region at (x,y) = 0, 0.51 m a time t 508 us after it entered the region. V. --- ---- 1) With what speed v did the particle enter the region containing the magnetic field? m/s 2) What is Fy, the x-component of the force on the particle at a time t = 169.3 µs after it entered the region containing the magnetic field. 3) What is Fy, the y-component of the force on the particle at a time t = 169.3 us after it entered the region containing the magnetic field. N 4) What is q, the charge of the particle? Be sure to include the correct sign. µC 5) If the velocity of the incident charged particle were doubled, how would B have to change (keeping all other parameters constant) to keep the trajectory of the particle the same? a. Increase B by a factor of 2 b. Increase B by less than a factor of 2 c. Decrease B by less than a factor of 2 d. Decrease B by a factor of 2 e. There is no change that can be made to B to keep the trajectory the same.
