If an electron in the lab has a kinetic energy equal to twice its rest energy, what is its speed in the lab?
 
  A) 0.87c B) 0.89c C) 0.94c D) 0.91c E) 0.84c

Question 2

Two parallel square metal plates, 8.4 cm on each side, are 2.5 mm apart and carry equal but opposite charge uniformly distributed over their facing surfaces.
 
  How much excess charge is there on each plate if the electric field between the plates has a magnitude of 2.0  106 N/C? (k = 1/40 = 8.99  109 N  m2/C2 )
