Figure shows three circular ars, each of radis R and total charge as indicated. The net electric potential at the centre of curvature is :

Figure shows a rod AB, which is bent in a 120^(@) circular arc of radius R. A charge (-Q) is uniformly distributed over rod AB. What is the electric field vecE at the centre of curvature O ?

A charge +Q is uniformly distributed along the circular arc of radius R as shown in the figure.The magnitude of the force experienced by the point charge +q place at the centre of curvature is (k=(1)/(4piepsilon_(0)))

The diagram shows a part of uniformly charged disc of radius R having surface charge densityo. If electric potential at the center O is Then find N. 1 N Х OR 280 R R/2

A charge Q is distributed uniformly on a ring of radius R as shown in the following diagrams. Find the electric potential at the center O of the ring. (a)

A solid of radius 'R' is uniformly charged with charge density rho in its volume. A spherical cavity of radius R/2 is made in the sphere as shown in the figure. Find the electric potential at the centre of the sphere.
