Assume the charged objects in Figure OQ19.15 are fixed. Notice that there is no sight line from the location of q 2 to the location of q 1 . If you were at q 1 , you would be unable to see q 2 because it is behind q 3 . How would you calculate the electric force exerted on the object with charge q 1 ? (a) Find only the force exerted by q 2 on charge q 1 . (b) Find only the force exerted by q 3 on charge q 1 . (c) Add the force that q 2 would exert by itself on charge q 1 to the force that q 3 would exert by itself on charge q 1 . (d) Add the force that q 3 would exert by itself to a certain fraction of the force that q 2 would exert by itself. (e) There is no definite way to find the force on charge q 1 . Figure OQ19.15

Solution Summary: The author explains that the force exerted on the object with charge q_1 is inversely proportional to the square of its distance between them.
Assume the charged objects in Figure OQ19.15 are fixed. Notice that there is no sight line from the location of q2 to the location of q1. If you were at q1, you would be unable to see q2 because it is behind q3. How would you calculate the electric force exerted on the object with charge q1? (a) Find only the force exerted by q2 on charge q1. (b) Find only the force exerted by q3 on charge q1. (c) Add the force that q2 would exert by itself on charge q1 to the force that q3 would exert by itself on charge q1. (d) Add the force that q3 would exert by itself to a certain fraction of the force that q2 would exert by itself. (e) There is no definite way to find the force on charge q1.
