Suppose ,one wishes to construct a`1.0`farad capacitor using circular discs. If the separaton between the discs be kept at `1.0`mm, what would be the rradius of the discs?

Calculate the capacitance of a parallel plate capacitor having circular discs of radii 0.05m each. The separation between the discs is 1 mm .

The plates of a paraller-plate capacitor are made of circular discs of radii 5.0 cm each .If the separation between the plates is 1.0 mm,What is the capacitance?

Each of the plates of a parallel plate capacitor is a circular disc of radius 5 cm. Find out its capacitance if the separation between the plates is 1 mm.

A unifrom disc is acted by two equal forces of magnitude F . One of them, acts tangentially to the disc, while other one is acting at the central point of the disc. The friction between disc surface and ground surface in nF . If r be the radius of the disc, then the value of n would be (in N )
