A thin nonconducting rod that carries a uniform charge per unit length of lambda

Question

A thin nonconducting rod that carries a uniform charge per unit length of lambda is bent into a circle of radius R as shown above. Express your answers in terms of lambda R, and the fundamental constants, Determine the electric potential V at the center C of the circle Determine the magnitude E of the electric held at the center C of the circle above. Another thin nonconducting rod that carries the same uniform charge per unit length lambda is bent into an are of a circle of radius R which subtends an angle of 2 theta as shown above. Express your answers in terms of theta and the quantities given above Determine the total charge on the rod Determine the electric potential V at the center of curvature C of the arc. Determine the magnitude E of the electric held at the center of curvature C of the arc. Indicate the direction of the electric field on the diagram above.
