Which of the following has a largest net force a i c charge a distance of i m from a -2 c charge. a 1 c charge a distance of 0.5 m from a - i c chargc. a 1( charge exactly halfway between a -i c charge and a i c charge separated by 2 m. a i c charge exactly halfway between two -2 c charges separated by 2 m. a i c charge a distance of 2m from a -4 c charge. a 1c charge is placed at the origin with a 2c charge placed at the coordinates (2.0). where should a charge of -4c be placed such that the net force on that charge is zero at x< 0 at 0

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?
