The electric field at the point x = 5.01 centimeter and y = 0 points in the positive x direction with a magnitude of 11.4 N/C. At the point x = 10.3 centimeter and y = 0 the electric field points in the positive x direction with a magnitude of 15.2 N/C. Assuming this electric field is produced by a single, point charge, calculate its location and also calculate its charge?
