Question

Banner ID There are 104 possible points. A 100% score is 100 points. Show all work. Include all steps. Put appropriate units on all numbers. Assume that all batteries are ideal, having no internal resistance. Some equations are on the last page 1. (12 pts) Two like charges are separated by some distance. Describe quantitatively what to the force exerted by one charge on the other if each if the following actions occur. numerically how the direction and magnitude of the force each circumstance compares to That a. The distance between the charges is tripled. b. The distance between the charges is halved. c. One of the charges is replaced by a charge of the same magnitude but opposite sign 2. (12 pts) In each of the drawings below, E- 6.0 N/C and d-2.0 m. For each diag potential difference between A and B. Show how your answer was calculated. A d B 30° a) b) c)

Explanation / Answer

1) F = kq1q2 / r^2

a) when the distance is tripled

The new force will be 1/9 times

b) when distance is halved

new force will be 4 times

c) when the sign is changed , the force will become attractive
