Question

Find out the capacitance of a spherical conductor of radius 10cm and give answer in c.g.s. units

Answer 1

Thus the value of the capacitance of the spherical conductor is C = 11.12 x 10^-12 F

Explanation:

We are given that:

Radius of spherical conductor "r" = 10 cm = 0.1 m

To find: Capacitance = ?

Solution:

The capacitance of a spherical capacitor is given by, C = 4πεoR

Noe put the value in above formula.

C = 4 x 3.14 x 8.854 × 10^-12 x 0.1

C = 1.256 x 8.854 × 10^-12

C = 11.12 x 10^-12 F

Thus the value of the capacitance of the spherical conductor is C = 11.12 x 10^-12 F

Answer 2

Thusn the capacitance of the spherical conductor is C = 11.12 x 10^-12 F

Explanation:

We are given that:

Radius of spherical conductor "r" = 10 cm

Convert it into meters = 10 cm / 100 = 0.1 m  ( Radius)

To find: Capacitance "C" = ?

Solution:

The capacitance of a spherical capacitor is given by, C = 4πεoR

Now put the value in above formula.

C = 4 x 3.14 x 8.854 × 10^-12 x 0.1

C = 1.256 x 8.854 × 10^-12

C = 11.12 x 10^-12 F

Hence the capacitance of the spherical conductor is C = 11.12 x 10^-12 F
