A test charge is placed successively at points I , II , and III . E +- I II III If edge effects are negligible, the force on the charge when it is at point III is 1. of equal magnitude and in the same di- rection as the force on the charge when it is at point I . 2. of equal magnitude and in the same di- rection as the force on the charge when it is at point II . 3. much less in magnitude than the force on the charge when it is at point II , but in the same direction. 4. equal in magnitude to the force on the charge when it is at point I , but in the oppo- site direction. 5. much greater in magnitude than the force on the charge when it is at point II , but in the same direction. Question 2, chap 26, sect 1. part 1 of 1 10 points A spherical capacitor consists of a conduct- ing ball of radius 7 cm that is centered inside a grounded conducting spherical shell of inner radius 10 cm. The Coulomb constant is 8 . 98755 × 10 9 N m 2 / C 2 . What charge is required to achieve a poten- tial of 497 V on the ball of radius 7 cm? Answer in units of C. Question 3, chap 26, sect 1. part 1 of 1 10 points A small electrically charged object is sus- pended by a thread between the vertical plates of a parallel-plate capacitor. The acceleration of gravity is 9 . 8 m / s 2 . A B vector E +- E 345 mg 15 nC θ θ =19 ◦ 2 . 6 cm What is the potential difference between the plates?...
