Capacitance (in F) of a spherical conductor with radius 1 m is :
Open in App
Solution
The correct option is A 1.1×10−10
Capacitance of spherical conductor =4πϵ0a
where a is radius of conductor.
Therefore, C=19×109×1=19×10−9
=0.11×10−9F=1.1×10−10F
Capacitance of spherical conductor =4πϵ0a
where a is radius of conductor.
Therefore, C=19×109×1=19×10−9
=0.11×10−9F=1.1×10−10F
