New problem. Suppose we have two positively charged particles a distance of 2 m apart from each other. Particle 1 has a charge of 3 C and particle 2 has a charge of 1.3 x 10^3 C. What
amount of electrostatic force exists between these two particles?
8.7 x 10^12 N
3.51 x 10^13 N
1.3 x 10^3 N

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
