First, calculate the magnitudes in newtons of the forces on charges q1 due to the other three charges. Use the appropriate conversion for length and charge. The notation should be as follows: if you are calculating the force q2 exerts on q1, then label that force f21. Fill in the blanks and enter the values of these forces without the unit below. Use three significant figures. f21 has a magnitude of ________ n, f31 has a magnitude of ________ n, and f41 has a magnitude of ________ n. When you enter the values, please use this format: for example if the force is 6.45e-3, enter 0.00645. Don't enter .00645 or 6.45e-3 or 6.45x10⁻³. Canvas will not recognize this format. You need three (3) significant figures and 0.00645 is correct. or 0.00200 also has 3 significant figures.
