The current in the LCR circuit shown in the figure is observed to lead the voltage in phase. Without making any other change in the circuit, a capacitor, of capacitance C_0 is (appropriately) joined to the capacitor C. This results in making the current, in the joined to the capacitor C. This results in making the current, in the modified' circuit, flow in phase with the applied voltage. Draw a diagram of the modified circuit and obtain an expression of C_0 in terms of Omega , L and C.

Assertion: Both natural and synthetic auxins have been used extensively in agricultural and horticultural practices. Reason: Auxin is widely applied in tea plantations and hedge-making.
