Two objects with charges Q1 and Q2 experience an electrical force of attraction of 8.0x10-4 N when separated by a distance of d. Determine the force of attraction if the same objects are separated by a distance of 2d and each object having double the charge.

The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is lal=9.1 µC, and the distance between them is d=4.6 mm. Determine the magnitude of the net force on charge 2 for each of the three drawings. d d 2 (b) d +q 1 (c) 2 Id +9

Four identical charged particles (g = +10.1 µC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 64.2 cm and W = 14.6 cm.
