JEE Main 2025 Physics question
A parallel plate capacitor was made with two rectangular plates, each with a length of = 3 cm and breath of = 1 cm. The distance between the plates is 3 μm. Out of the following, which are the ways to increase the capacitance by a factor of 10 ? A. = 30 cm, = 1 cm, = 1 μm B. = 3 cm, = 1 cm, = 30 μm C. = 6 cm, = 5 cm, = 3 μm D. = 1 cm, = 1 cm, = 10 μm E. = 5 cm, = 2 cm, = 1 μm Choose the correct answer from the options given below :
