                I need to sketch a 45 deg - 45 deg - 90 deg triangle and indicate the lengths of each side assuming the hypotenuse is = to 1 meter

    This not about physics.
Use graph paper or an straight-edge with a right angle corner to draw two lines at right angles meeting at a point. Make the two lines of equal length. Draw the hypotentuse between the other two ends of the lines. If you choose a scale that calls the hypotenuse length 1 meter, the two equal sides will have a length of 0.707 meters. 1/(sqrt2)

    In the figure, charge  = 2.1 ×  is placed at the origin and charge  is placed on the -axis, at  = -0.20 m. Where along the -axis can a third charge  be placed such that the resultant force on this third charge is zero?
