Q1. Five identical charges q = +3.0mC are arranged in a half-circle, each charge 46 degrees from the next. The radius of the circle r = 0.12m. A point charge of q0 = +1.0 mC sits in the center of the circle. What is the magnitude of net force acting on the center charge?

Q2. Plan the velocity/time graphs of the following motions:

a) a tiger that is speeding up at a uniform rate of acceleration while moving in negative direction.

b) An iguana that is slowing down at a uniform rate of acceleration while moving in positive direction.

c) A camel that is slowing down at a uniform rate of acceleration while moving in negative direction.
