Problem 6 Two opposite charges are placed on a line as shown in the figure below. 34 The charge on the right is three times the magnitude of the charge on the left.Besides infinite, where else can electric field possibly be zero? 1. between the two charges. 2.to the right of the charge on the right. 3.to the left of the charge on the left 4. the electric field is nowhere zero. Answer:3.The electric field from the positive charge E and the electric field from the negative charge E are shown for different regions with the arrow size indicative of the magnitude in the figure below. 30 飞9 +E。 3q E。← The only place the fields can cancel is to the left of the negative charge.For the region to the right of the charge of greater magnitude,the smaller charge is further away and so the magnitude of the field of the smaller charge can never equal the magnitude of the field of the larger charge. 66 Problem 6 Two opposite charges are placed on a line as shown in the figure below.

Answer: 3. The electric field from the positive charge ! E+3q and the electric field from the negative charge ! E!q are shown for different regions with the arrow size indicative of the magnitude in the figure below. The only place the fields can cancel is to the left of the negative charge. For the region to the right of the charge of greater magnitude, the smaller charge is further away and so the magnitude of the field of the smaller charge can never equal the magnitude of the field of the larger charge
