A source of sinusoidal emf with constant voltage is connected in series with an oscillating circuit with quality factor `Q=100`. At a certain frequency of the external voltage the heat power generated in the circuit reached the maximum value. How much `(` in per cent`)` should this frequency be shifted to decrease the power generated `n=2.0` times ?
