Particles q1, 92, and q3 are in a straight line. Particles q1 = -28.1 uc, q2 = +25.5 uc, and
q3 = -47.9 PC. Particles q1 and q2 are separated
by 0.300 m. Particles q2 and q3 are separated by
0.300 m. What is the net force on q3?

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement
