A point charge with charge q 1 = + 5 .00 nC is fixed at the origin. A second point charge with charge q 2 = − 7 .00 nC is located on the x axis at x = 5 .00 m . Where along the x axis will a third point charge of q = + 2 .00 nC charge need to be for the net electric force on it due to the two fixed charges to be equal to zero?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
