Asmall object has a mass of 2.9 10-3 kg and a charge of -36 µc. it is placed at a certain spot where there is an electric field. when released, the object experiences an acceleration of 2.49 103 m/s2 in the direction of the +x axis. determine the magnitude and direction of the electric field.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
