A parallel plate capacitor was made with two rectangular plates, each with a length of ℓ = 3 cm and breath of b = 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. ℓ = 30 cm, b = 1 cm, d = 1 µm
B. ℓ = 3 cm, b = 1 cm, d = 30 µm
C. ℓ = 6 cm, b = 5 cm, d = 3 µm
D. ℓ = 1 cm, b = 1 cm, d = 10 µm
E. ℓ = 5 cm, b = 2 cm, d = 1 µm
