A particle is acted upon by only two forces, one conservative and one nonconservative, and neither being a forceof friction, as it moves from point A to point B. The kinetic energies of the particle at points A and B are equal if .

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples
