Physics - Capacitor Question with Solution | TestHub

A parallel plate capacitor was made with two rectangular plates, each with a length of $l=3\mathrm{cm}$ and breath of $\mathrm{b}=1\mathrm{cm}$. The distance between the plates is $3\mu \mathrm{m}$. Out of the following, which are the ways to increase the capacitance by a factor of 10 ? A. $l=30\mathrm{cm},\mathrm{b}=1\mathrm{cm},\mathrm{d}=1\mu \mathrm{m}$ B. $l=3\mathrm{cm},\mathrm{b}=1\mathrm{cm},\mathrm{d}=30\mu \mathrm{m}$ C. $l=6\mathrm{cm},\mathrm{b}=5\mathrm{cm},\mathrm{d}=3\mu \mathrm{m}$ D. $l=1\mathrm{cm},\mathrm{b}=1\mathrm{cm},\mathrm{d}=10\mu \mathrm{m}$ E. $l=5\mathrm{cm},\mathrm{b}=2\mathrm{cm},\mathrm{d}=1\mu \mathrm{m}$ Choose the correct answer from the options given below:
