A resistor with a resistance of 360  is in a series circuit with a capacitor of capacitance 7.3  10-6 F.
 
  What capacitance must be placed in parallel with the original capacitance to change the capacitive time constant of the combination to three times its original value?

Question 2

A small 4.0-C charge and a small 1.5-C charge are initially very far apart.
 
  How much work does it take to bring them to a final configuration in which the 4.0-C charge is at the point x = 1.0 mm, y = 1.0 mm, and the 1.5-C charge is at the point x = 1.0 mm, y = 3.0 mm? (k = 1/40 = 8.99  109 N  m2/C2 )
  A) 27 J
  B) 13.5 kJ
  C) 54 J
  D) 13.5 J
