Question
As shown in figure, if the point 
is earthed and the point 
is given a potential of 2000 V, then the potential at point 
will be
- 400 V
- 500 V
- 1000 V
- 1300 V
The correct answer is: 500 V
Equivalent capacitance between points 
is
Now equivalent capacitance between points 
is
Charge on capacitor of capacity 5
is
(Since, potential at the point will be zero)
Now, potential difference across capacitor of 5 is
=1500volt
As,
volt
Hence, 
volt.
