A point charge Q1 = +6.0 nC is at the point (0.30 m, 0.00 m); a charge Q2 = -1.0 nC is at (0.00 m, 0.10 m), and a charge Q3 = +5.0 nC is at (0.00 m, 0.00 m).
 
  What are the magnitude and direction of the net force on the +5.0-nC charge due to the other two charges? (k = 1/40 = 9.0  109 N  m2/C2 )

Question 2

At a certain instant the current flowing through a 5.0-H inductor is 3.0 A. If the energy in the inductor at this instant is increasing at a rate of 3.0 J/s, how fast is the current changing?
 
  A) 0.20 A/s B) 0.10 A/s C) 0.80 A/s D) 0.40 A/s
