1. Consider two charges which lie on the x-axis. QA is at the origin. It has a charge of -3.0C and a mass of 25.0g. QB is at x = -0.50m. It has a charge of -6.0C and a mass of 12.5g. Compare the force of A on B to the force of B on A, and compare the initial accelerations of charge B and charge A if they were suddenly released from their locations. You may neglect all other forces on the charges except the electric forces due to one another. 2. Three very small, charged spheres, each with mass 4.0x104 g, are placed at the corners of a triangle (see figure). The charges are +7.0 , -8.0 C, and -6.0 C, and the distance between each charge is 1.20m. Calculate the magnitude and direction of the net electric force on a +5.0 C charge placed at the midpoint between Q2 and Q3. 3. For the setup in the previous problem, calculate the magnitude and direction of the net electric force on Q due to the other two charges. Note that each angle of an equilateral triangle has a 60 angle. 1.20 m Q2=-8.0 C Q = +7.0 C 1.20 m 1.20 m Q3=-6.0 C 1. Consider two charges which lie on the x-axis. QA is at the origin.
