Question

In the given circuit, charge Q2 on the 2μF capacitor changes as C is varied from 1μF to 3μF. Q2 as a function of ′C′ is given properly by : (figures are drawn schematically and are not to scale) :-
       

Options

A.
B.
C.
D.

Solution

  
Ceq =                  Q = Ceq.E
Q2 =               
 = 2E
Q2/when C = 1μF = 2E
Q2/when C = 3μF = 2E = E
