A capacitor is discharging through a resistor $R$. Consider in time $t_1$, the energy stored in the capacitor reduces to half of its initial value and in time $t_2$, the charge stored reduces to one eighth of its initial value. The ratio $\frac{t_1}{t_2}$ will be\\
(1) $\frac{1}{2}$\\
(2) $\frac{1}{3}$\\
(3) $\frac{1}{4}$\\
(4) $\frac{1}{6}$
