Find the electric field at the centre of a uniformly charged semicircular ring of radius R. Linear charge density is lamda

Find the electric field and potential at the centre of curvature of a uniformly charged semicircular rod of radius R with a total charge Q in SI. lambda is the linear charge density.

The electric field at the centre of a uniformly charged ring is zero. What is the electric field and potential at the centre of a half ring if the charge on it be Q and its radius be R ?

What is the intensity of the electric field at the centre of a charged ring?

A ring of radius R has uniformly distributed charge q. A point charge Q is placed at the centre of the ring. (a) Find the increase in tension in the ring after the point charge is placed at its centre. (b) Find the increase in force between the two semicircular parts of the ring after the point charge is placed at the centre. (c) Using the result found in part (b) find the force that the point charge exerts on one half of the ring.
