A student makes the claim that the space around a charged particle will exert a force on any other charged particle that is placed within this space. If an object is placed between two charged metal
plates, one plate that is positively charged and one plate that is negatively charged, which
argument BEST supports the student's claim?
An object with a positive charge will be attracted to the positive plate. An object with a negative charge will be attracted to the negative plate.
An object with a positive charge will move toward the negative plate.
An object with a negative charge will remain stationary between the plates.

You are the coordinator for a program that is going to take place at night in a rectangular amphitheater in the mountains. you will have no access to any electricity, but you must be able to illuminate the entire grounds. you know the intensity of the light from a lantern varies inversely as the square of the distance from the lantern. suppose the intensity is 90 when the distance is 5 m. a. write an equation to model the situation. b. solve for the constant of variation. c. write the equation to model the situation using the constant () of variation. d. you have been given lanterns with 40 light intensity. use your equation to solve for the distance from the lantern. e. you need to illuminate 225 km. how many meters do you need to light? f. how many lanterns will you need?
