Assertion: In the circuit shown in figure with a dielectric slab is inserted in `C_2`, the potential difference across `C_2` will decrease.


Reason: By inserting the slab a current will flow in the circuit in clockwise direction.

Options

A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. If Assertion is true, but the Reason is false.
D. If Assertion is false but the Reason is true.

Answer

B

Explanation

By inserting dielectric slab, value of `C_2` is increased `PD` across `C_2` will decrease. If `C_2` is increased, charge on capacitors will also increase. So, positive charge or current flows in clockwise direction.
