**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:

6.5x10^-6N

0.0195N

2.17x10^-5N

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:

1.09x10^-7C

1.21x10^-17C

6.04x10^-20C

None of the above.

**Question 3** (33.3 points)

Question 3 options:

4.10x10^-15C

3.02x10^-20C

1.03x10^-15C

None of the above
