Problem 1 (25 points)
This problem deals with 3 positive charges, Q0, 2Q0 and 3Q0.
Consider the configuration shown below, with a +2Q0 at
position x0=0 and a positive charge Q0 at position x1 along the xaxis.

Problem 1: Kinematics (15 pts)
A particle moves along a straight line x. At time t = 0, its position is at x = 0. The velocity,
V , of the object changes as a function of time, t, as shown in the gure. V is in m/s, x is in
meter, and t is in seconds.
