Three charges are arranged in a triangle. The first charge has a magnitude of 8.3 nC and is located at the origin. The second charge is at the point (4.5 cm, 0) and has a magnitude of 22 nC. The third charge is at point (1.5 cm, 2.0 cm) and has a charge of 17 nC. What is the magnitude and direction of the total force on the third charge from the other two charges?  

As a bee picks up pollen, it acquires a charge. In video of a bee feeder, you notice that a grain of pollen seems to be floating 4.0 mm above the center of mass of a bee for a moment, before the bee flies away and the pollen grain falls. If the pollen is known to typically have a mass of 7.0 ng, and carry a charge of 3.5 fC. How much pollen has the bee picked up (in grams)?
