Three point charges lie along a straight line as shown in the figure below, where q1 = 3.51 μC, q2 = 8.03 μC, and q3 = - 8.72 μC. The separation distances are d1 = 7.28 cm and d2 = 2.34 cm. Calculate the magnitude of the net electric force on q1.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
