Take the potential of the point B as shown in the figure to be 100 V.
A
Find the potentials at the point C and D.
B
If an uncharged capacitor is connected between C and D, then find the amount of charge that will appear on this capacitor 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
[ 700/3 V at each point, zero]
Sol.
Charge on 30µF = 200 × 20 = 4000 µC
so V C – V B = 
⇒ V C = 100 + 
V
also charge on 20µF
= 200 × 
µC
so V D – V B = 
V D = 100 + 
V
⇒ V C – V D = 0
