Three charges lie along the x-axis. One positive charge, q1 = 4.80*10^-18 C, is at x = 3.24 m, and another positive charge, q2 = 1.60*10^-19 C, is at the origin. At what point on the x-axis must a negative charge, q3, be placed so that the resultant force on it is zero?

If the new moon happens on january 15th, what shape will it be on february 6th?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
