A uniformly charged insulating rod of length 'L has a total charge 'Q'. It is bent into the shape of a semicircle as shown in the figure. Electric field strength at O can be expressed as O у

A conductor is bent in the form of concentric semicircles as shown in the figure. The magnetic field at the point O is

A rod of length L has a total charge Q distributed uniformly along its length. It is bent in the shape of a semicircle. Find the magnitude of the electric field at the centre of curvature of the semicircle.

A rod of length L has a total charge Q distributed uniformly along its length. It is bent in the shape of a semicircle. Find the magnitude of the electric field at the centre of curvature of the semicircle.

A positive charge Q is uniformly distributed across a rod of length L. The rod is then bent in the form of a semicircle. What will be the electric field intensity at the centre of curvature of the semicircle thus formed?

A positive charge Q is uniformly distributed along the length L of a rod. It is bent in the shape of a square. Calculate electric field intensity at the centre of the square.

If one penetrates a uniformly charged solid sphere, the electric field strength E
