What main features do you observe from this tabular representation?

shows, in cross section, a plastic, spherical shell with uniform charge Q =-16e and radius R = 10cm. A particle with charge q = + 5e is at the center. What is the electric field (magnitude and direction) at (a) point P _(1) at radial distance r _(1) = 6.00cm and (b) point P _(2) at radial distance r _(2) =12.0cm ?

A point charge q = - 8.0 nC is located at the origin. Find the electric field vector at the point x = 1.2 m, y = -1.6 m.

In Fig., positive charge q = 9.25 pC is spread uniformly along a thin nonconducting rod of length L = 16.0 cm. What are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the electric field produced at point P, at distance R = 6.00 cm from the rod along its perpendicular bisector ?
