Answer :
After leaving the provided switch at the given position for a longer time, then its moves given switch from a to b. At t = 0, the left part of the plate C has charge q = max and therefore, the current flowing through it is zero.
Oscillation is the repetitive or periodic variation, usually in time, of a few degree approximately a crucial value or extra one-of-a-kind states. Familiar examples for all oscillation encompass a swinging type of pendulum with alternating current. A wave is stated to oscillate, which means to transport to and fro in a regular, repeating way.
This fluctuation may be among extremes for all position, like force or quantity. Different sorts of waves have one-of-a-kind sorts of oscillations.
Longitudinal types of waves: here oscillation is parallel route of the wave.
The maximum charge stored in the capacitor is,
Q = CE ------(1)
i = 0
At t = t/4, the left part of the plate C has charge q = 0 and therefore, the current flowing through it is clockwise.
i = clockwise
At t = t/2, the left part of the plate C has charge q = -9max and therefore, the current flowing through it is zero.
i = 0
At t = 3t/4, the left part of the plate C has charge q = 0 and therefore, the current flowing through it is counter clockwise
i = counter clockwise
At t = 0, the left part of the plate C has charge q = max and therefore, the current flowing through it is zero.
