A simple RC circuit consists of a 1-micro-Farads capacitor in series with a 2800-ohms resistor, a 6-V battery, and an open switch.  Initially, the capacitor is uncharged.  How long after the switch is closed will the voltage across the capacitor be 4.1 V?

Which one of the following statements concerning electrostatic situations is false?

At which point (or points) is the electric field zero N/C for the two point charges shown on the x axis?

Two charges are located on the x axis: q1 = +4.7 μC at x1 = +3.6 cm, and q2 = +4.7 μC at x2 = -3.6 cm. Two other charges are located on the y axis: q3 = +2.3 μC at y3 = +4.4 cm, and q4 = -8.7 μC at y4 = +6.6 cm. Find the magnitude and the direction of the net electric field at the origin.
