Question

a. The electric fieldis never zero in the vicinity of these charges. b. The electric fieldis zero somewhere on the x axis to the left of the +4q charge. c. The electric fieldis zero somewhere on the x axis to the right of the –2qcharge. d. The electric fieldis zero somewhere on the x axis between the two charges, but thispoint is nearer to the –2q charge. e. The electric fieldis zero at two points along the x axis; one such point is to theright of the –2q charge and the other is to the left of the+4q charge. Two charges are located on a line. The charge on the left has a +4microC value. The charge on the right has a -2 microC value. Atwhich point is the electric field zero for the two point chargesshown on the x axis? a. The electric fieldis never zero in the vicinity of these charges. b. The electric fieldis zero somewhere on the x axis to the left of the +4q charge. c. The electric fieldis zero somewhere on the x axis to the right of the ?2qcharge. d. The electric fieldis zero somewhere on the x axis between the two charges, but thispoint is nearer to the ?2q charge. e. The electric fieldis zero at two points along the x axis; one such point is to theright of the ?2q charge and the other is to the left of the+4q charge.

Explanation / Answer

Two charges are located on a line. The charge on the left hasa +4C value. The charge on the right has a -2C value. Then The electric field is zeroat two points along the x axis; one such point is to the right ofthe –2q charge and the other is to the left of the +4qcharge. So answer is (e). Then The electric field is zeroat two points along the x axis; one such point is to the right ofthe –2q charge and the other is to the left of the +4qcharge. So answer is (e).
