Three identical 3.0-C charges are placed at the vertices of an equilateral triangle that measures 30 cm on a side.
 
  What is the magnitude of the electrostatic force on any one of the charges? (k = 1/40 = 9.0  109 N  m2/C2 )
  A) 1.8 N B) 2.0 N C) 2.2 N D) 2.4 N E) 1.6 N

Question 2

If a point charge of -30 C experiences an electrostatic upward force of 27 mN at a certain location in the laboratory, what are the magnitude and direction of the electric field at that location?
 
  What will be an ideal response?
