Question

find the capacitance of an isolate sphere of radius 15 cm​

Answer 1

Answer:

Capacitance of the spherical conductor =4π∈₀×R

1/(4π∈₀) = 9×10⁹ Nm²/C²

C = (15 ×10⁻²)/( 9× 10⁹)

C = 1.66 × 10⁻¹¹ F

C = 1.7 × 10⁻¹¹ F

Answer 2

$\huge\bf{Question}$

Find the capacitance of an isolate sphere of radius 15 cm.

$\huge\bf{Answer:-}$

$\small\bf{For\:an\:identical\:spherical\:conductor}$

$\small\bf{C\:\: = 4π∈_{o} \times R}$

$\small\bf{R\:\: = 15 \:cm\: }$

$\small\bf{We\:Know\:that\: ,}$

$\bf{\frac{1}{4π∈_{o}} \: = \: 9 \times \ 10^{9} \ Nm^{2} \ C^{-2}}$

$\bf{C\: = \:\frac{15 \times \ 10^{-2}}{9 \times \ 10^{9}}}$

$\small\bf{C\:\: = \:\: 1.7\times10^{-11}F}$
