[asd123]

A 10-F capacitor in an LC circuit made entirely of superconducting materials (R = 0 ) is charged to 100 C. Then a superconducting switch is closed. At t = 0 s, plate 1 is positively charged and plate 2 is negatively charged. At a later time, V_ab = +10 V. At that time, V_dc is
 
   

   
  a.
  0 V.
   
  b.
  3.54 V.
   
  c.
  5.0 V.
   
  d.
  7.07 V.
   
  e.
  10 V.

Question 2

All three circuits below have R = 100 , C = 1.0 mF, and emf = (5.0 V) sin (377 t). The inductors in (B) and (C) are placed sufficiently far apart so that they do not alter one another's inductance. Such inductors add combine like resistors. Which statement regarding the angular resonance frequencies _A, _B, and _C is correct?
 
 
 
   
  a.
  _C > _A = _B
   
  b.
  _C < _A = _B
   
  c.
  _A = _B = _C
   
  d.
  _B < _A = _C
   
  e.
  _B > _A = _C
