The electric field at the point x = 15.0 cm and y = 0 points in the positive x direction with a magnitude of 10.0 N/C. At the point x = 30.0 cm and y = 0 the electric field points in the positive x direction with a magnitude of 30.0 N/C. Assume that this electric field is produced by a single, point charge.
(a) Find the location of the point charge. (x, y) = ?
(b) Find the sign and magnitude of its charge.
