Document Summary

Each of two small non-conducting spheres is charged positively, the combined charge being. A particle (charge = +40 c) is located on the x axis at the point x = 20 cm, and a second particle (charge = 50 c) is placed on the x axis at x = +30 cm. What is the magnitude of the total electrostatic force on a third particle (charge = 4. 0 c) placed at the origin (x = 0)? a. 41 n b. 16 n c. 56 n d. 35 n e. 72 n. In the gure, if q = 30 c, q = 5. 0 c, and d = 30 cm, what is the magnitude of the electrostatic force on q? a. 15 n b. 23 n c. zero d. 7. 5 n e. 38 n. A charge of +80 c is placed on the x axis at x = 0. A second charge of 50 c is placed on the x axis at x = 50 cm.
