Question

If the distance between the plates of a circular parallel plate capacitor of diameter 40mm whose capacity is equal to that of a metallic sphere of radius 1m will be

Answer 1

Answer:

Capacitance of metal sphere and capacitance of parallel plates are equal according to the question,

i.e,

4π€R=A€/d. (A=πr*2)

4*R=r*2/d

So,d=20×20/4000=0.1mm
