A particle with a charge of +4.0 C has a mass of 5.0 g. What magnitude electric field directed upward will exactly balance the weight of the particle?
 
  A) 4.1  104 N/C
  B) 8.2  104 N/C
  C) 4.4  104 N/C
  D) 1.2  104 N/C
  E) 5.1  104 N/C

Question 2

A geophysicist measures the magnetic force on a proton that is moving vertically downward at a point 1.996 km/s at the earth's equator. At that location, the earth's magnetic magnetic field is horizontal and has a strength of 0.40  10-4 T.
 
  What are the magnitude and direction of the force she will measure? (e = 1.60  10-19 C)
