Question

calculate the capacitance of metallic sphere of radius 1m.​

Answer 1

Answer:

1.11× 10^-10 F

Explanation:

According to the given question,

Radius of the sphere = r = 1 m

And we are asked to find the capacitance of the metallic sphere.

We know,

• C =4πε × r

Where C = capacitance of the metallic sphere.

By putting the values we get,

• C = 1/9×10^9

As 1/4πε = 9×10^9 from electrostatic force

So, 4πε = 1/9×10^9

Thus, C = 1×10^-9 /9

• C = (10/9) × 10^-10

• C = 1.11× 10^-10 F

Therefore, capacitance of the metallic sphere will be 1.11× 10^-10 F, when radius of the sphere is 1 m.
