A small plastic rod electrified with a charge of 2.0 x 10^-7 C is placed 3.0 cm away from point A. The electric field generated by the rod at the position of point A has intensity E. An electron is placed at point A and then released from rest. Determine: (1) The intensity of the electric force acting on the electron. (2) The acceleration of the electron at the moment it is released.Answer sheet:

A technician from an electronics company is working on a circuit involving three capacitors in series. The capacitors have capacitances of 6μF, 8μF, and 12μF, respectively. Assuming the potential difference applied to the capacitors is 60V, determine the charge stored in each capacitor and the equivalent capacitance of the series configuration.

A motor operates according to the Carnot cycle between two thermal sources. The hot source is at a temperature of 500 K and the cold source at 300 K. Determine the efficiency of the motor, knowing that the efficiency of the Carnot cycle is calculated by the expression 1 - (Tcold/Thot), where Tcold and Thot are the temperatures of the cold and hot sources, respectively. Discuss briefly the importance of the maximum efficiency of the Carnot cycle in practical applications of thermal engines.
