Problem 1 Three equal charges Q are at three of the corners of a square of side d. A fourth charge Q of equal magnitude is at the center of the square (as shown in the figure below). Which one of the arrows shown represents the net force acting on the charge at the center of the square? Explain how you arrived at your answer. +Q d +Q A C B +Q D +Q Problem 2 Three identical 3 µC charges are placed at the vertices of an equilateral triangle that measures 30 cm on a side. What is the magnitude of the electrostatic force on any one of the charges? Problem 3 Two tiny particles having charges 20 µC and -8 µC are separated by a distance of 20 cm. What are the magnitude and direction of electric field midway between these two charges?

The wheel rolls without slipping, and its position is controlled by the motion of the slider B. If B has a constant velocity of 10 in./sec to the left, determine the angular velocity of AB and the velocity of the center O of the wheel when $\theta$ = 0. The angular velocity of AB is positive if counterclockwise, negative if clockwise. The velocity of O is positive if to the right, negative if to the left.
