Air pollution is a concern because it is both a local and problem.

A5 nc point charge is at the origin and a second 3 nc point charge is on the x-axis at x = 0.8 m. find the magnitude and direction of the electric field on the x-axs at x = 0.2 m. you may express the direction by letting positive field mean the positive x direction

Avalue that describes how heavy an object is and is related to the force of gravity is

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
