In the circuit shown in the figure, resistor A has three times the resistance of resistor B. Therefore;

For the circuit below, R1 = 2000 Ω, R2 = 3000 Ω, R3 = 4000 Ω, and emf = 12V; use Kirchoff’s Laws to find the following: NOTE: Answer should be in decimals (i.e 3.1×10-6 would be 0.0000031) and include the unit with your answer.   The current through resistor R1 is [I1]. The current through resistor R2 is [I2]. The current through resistor R3 is [I3]. The potential difference between pair VA – VB is [VAB]. The potential difference between pair VA – VC is [VAC]. The potential difference between pair VC – VB is [VCB]. The power in resistor R1 is [P1]. The power in resistor R2 is [P2]. The power in resistor R3 is [P3].

What is the electric potential at point P located at the center of the square of point charges q1 = +12 nC, q2 = -24 nC, q3 = +31 nC, q4 = +14 nC with distance d = 1.3 m? NOTE: Include the unit with your answer.  

Six charged particles surround particle 7 at radial distances of d = 1.0 cm, as drawn. The charges are q1 = +2e, q2 = +4e, q3 = +e, q4 = +4e, q5 = +2e, q6 = +8e, q7 = +6e, with e = 1.602 x 10-19 C.   Show on a free body diagram the direction of the forces on particle 7 due to the surrounding particles. NOTE: The free body diagram needs to be provided along with your work and uploaded into CANVAS by 7:15PM. What is the magnitude of the net electrostatic force on particle 7? NOTE: Include the unit with your answer.
