Question 1 (33.4 points)


Assume that the length of a string holding the

suspended sphere (s) is 30cm long. A guided sphere (g) is brought close to sphere s and they touch. Then sphere s is repelled by sphere g a distance of 1 cm from equilibrium. What is the electrosatic repulsion between the spheres? Assume: m*g=6.5x10^-4 N.

Question 1 options:




None of the above

Question 2 (33.3 points)


Assuming the answer from the previous question is 2.17x10^-5N the charge on both spheres (combined) from the previous question AFTER they touch and then move away from each other with a separation of 0.5cm between them?

Question 2 options:




None of the above.

Question 3 (33.3 points)


Using the answer from the previous question what is the charge on each spheres AFTER they touch?

Question 3 options:




None of the above
