    Electric field direction on a grounded conducting sphere

    I am required to find the direction of the electric field on the surface of a grounded conducting sphere in the proximity of a point charge ##+q##. The distance between the center of the sphere and the point charge is ##d## and using the method of images we find that the charge of the sphere is...

    Electric field of a non-uniformly charged ring

    Homework Statement Calculate the magnitude and direction of the electric field due to the ring in the point P on the z-axis. Homework Equations Charge distribution on the ring is given by λ(φ)=λ_0\cdot sin(φ). This should result in the total charge on the ring being zero. Electric field is...
