Question

A negative charge of q = -3.1 × 10-17C and m = 4.7 × 10-26 kg enters a magnetic field B = 0.55 T with initial velocity v = 230 m/s, as shown in the figure. The magnetic field points into the screen. q = -3.1 × 10-17C m = 4.7 × 10-26 kg B = 0.55 T v = 230 m/s

  13% Part (a) Which direction will the magnetic force be on the charge?

  13% Part (b) Express the magnitude of the magnetic force, F, in terms of q, v, and B.
  13% Part (c) Calculate the magnitude of the force F, in newtons.
  13% Part (d) Under such a magnetic force, which kind of motion will the charge undergo?
  13% Part (e) Express the centripetal acceleration of the particle in terms of the force F and the mass m.
  13% Part (f) Calculate the magnitude of a, in meters per square second.
  13% Part (g) Express the radius, R, of the circular motion in terms of the centripetal acceleration a and the speed v.
  13% Part (h) Calculate the numerical value of the radius R, in meters.
