A coaxial cable has an inner cylindrical conductor surrounded by cylindrical insulation and an outer cylindrical conducting shell. The outer shell carries the same current but in the opposite direction from that in the inner conductor as shown. If the coaxial cable sits in a uniform magnetic field directed upwards with respect to the cable, the effect of the field on the cable is
 
   

   
  a.
  a net force to the left.
   
  b.
  a net force to the right.
   
  c.
  a net force upwards.
   
  d.
  no net force but a slight shift of the inner conductor to the left and the outer conductor to the right.
   
  e.
  no net force but a slight shift of the inner conductor to the right and the outer conductor to the left.

Question 2

A magnetic field is directed out of the page. Two charged particles enter from the top and take the paths shown in the figure. Which statement is correct?
 
   

   
  a.
  Particle 1 has a positive charge and particle 2 has a negative charge.
   
  b.
  Both particles are positively charged.
   
  c.
  Both particles are negatively charged.
   
  d.
  Particle one has a negative charge and particle 2 has a positive charge.
   
  e.
  The direction of the paths depends on the magnitude of the velocity, not on the sign of the charge.
