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

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. a rider is towed at a constant speed by a rope that is at an angle of 15 ∘ from horizontal. the tension in the rope is 1900 n. the force of the sail on the rider is 30∘ from horizontal. what is the weight of the rider? express your answer with the appropriate units.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
