A particle has 3 x 10^15 eV has a charge of 3uC is placed on a certain field. a. solve for electric potential difference, assuming the energy flow comes form a higher value going to 0
b. Solve for velocity of particle
c. solve for equipotential if the other point has an electric potential of 5V less than the answer in a.

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.
