Question

5.
The capacity of a parallel plate capacitor with no
dielectric substance but with a separation of 0.4 cm
is 2 uF. The separation is reduced to half and it is
filled with a dielectric substance of value 2.8. The
final capacity of the capacitor is
(a) 11.2 uF (b) 15.6 °F (C) 19.2 uF (d) 22.4 juF​

Answer 1

Answer:

here

Explanation:

11.2 micro farad

as distance between the plates is halved the capacitance doubles and then multiply it with dielectric constant k=2.8
