The electric flux through a spherical Gaussian surface of radius r=20.0cm, with a uniformly charged, spherical conducting shell at its center, is ΦE =−2.30 × 104 N·m2/C. T c. How many excess electrons or protons does this sphere contain? d. f the conductor has a radius of R = 10.0 cm, what is its surface charge density? e. What is the electric field strength at the surface of the conductor?

A uniform electric field of magnitude 43.1N/C is parallel to the x axis. A circular loop of radius 25.7cm is centered at the origin with the normal to the loop pointing 27.4 above the x axis. A). Calculate the electric flux in, newton squared meters per coulomb, through the loop.  B).  To what angle, in degrees from the positive x axis, should the normal of the loop be rotated so that the flux through the loop becomes 0.419N⋅m2/C?
