$13.33$

Vedclass · Answer

(d) $C = \frac{{A{\varepsilon _0}}}{d} = 10\,\mu F$
${C_1} = \frac{{A{\varepsilon _0}}}{{d - t + \frac{t}{k}}} = \frac{{A{\varepsilon _0}}}{{d - \frac{d}{2} + \frac{d}{{2k}}}} = \frac{{A{\varepsilon _0}}}{{\frac{d}{2}\left( {1 + \frac{1}{2}} ight)}} = \frac{4}{3}.\frac{{A{\varepsilon _0}}}{d}$
 ${C_1} = \frac{4}{3} 	imes 10 = 13.33\,\mu F$
