If the area of the plates of a parallel plate capacitor is halved, and the separation between the plates tripled, all while the

Scorpion4ik [409]

Answer:

Explanation:

The capacitance of a parallel plate capacitor is given by

$C=\frac{\epsilon _{0}A}{d}$

where A is the area of plates and d is the separation between the plates.

Now the area is halved and the separation is tripled.

The new capacitance is

C' = C / 6

Initial potential energy is given by

$U=\frac{q^{2}}{2C}$

here the charge is constant

The new energy is given by

$U'=\frac{6q^{2}}{2C}$

U' = 6 U

The energy becomes six times the initial value.

A spherical capacitor is formed from two concentric, spherical, conducting shells separated by vacuum. The inner sphere has radi

galina1969 [7]

Answer:

19 cm

Explanation:

inner radius, a = 16 cm, C = 113 p F = 113 x 10^-12 F

Let b cm be the radius of outer sphere.

The formula of capacitance of spherical capacitor is given by

C = 4π∈0 a b / (b - a)

a b / ( b - a) = C / 4π∈0

a b / ( b - a ) = 113 x 10^-12 x 9 x 10^9

a b / ( b - a ) = 1.017

16 x 10^-2 x b x 10^-2 = 1.017( b - 16) x 10^-2

0.16 b = 1.017 b - 16.272

0.857 b = 16.272

b = 19 cm
