In some of these problems you may need to know that the mass of an electron is 9.11 x 10^-³¹ kg, the mass of a proton is 1.67 x 10^-²⁷ kg, the electric charge of the electron is -1.6 x 10^-¹⁹ C, and the charge of a proton is 1.6 x 10^-¹⁹ C.

E field lines for a field created by an arrangement of charged objects are shown in Figure P15.6. (a) Where are these objects located, and what are the signs of their electric charge? (b) What else can you determine using the information? Give two examples.
