In the given circuit, initially
is closed and
is open Then
is opened and
is closed If
and
are charges on
and
and
and
are the voltages respectively, then

Text Solution
Verified by ExpertsThe correct answer is:
A
From the figure, when
is closed and
is open,
is charged to potential V acquiring a total charge 

When
is open and
is closed, battery is cut off
and
are in parallel. The charge on
is shared between
and
such that 
As after is no loss of charge,
