Charge x has twice as much charge as particle y. the two charges are placed near each other. compared to the force on particle x, what is the force on particle y? question 8 options: four times less two times more the same none of these

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
