How does the electrostatic potential energy of a system of two positive point charges change when the distance between them is tripled: (a) it is reduced to one-third its original value, (b) it is reduced to one-ninth its original value, (c) it is unchanged, or (d) it is increased to three times its original value?

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
