An example of the experimental setup from the lab "Electrostatics and Coulomb's Law" is shown below. If the distance between the two pith balls r = 7, and the angle of one string with the vertical =5 find the value of the electric charge (in nano Coulombs nC) on one of the pith balls (Hint: remember to use mass "0.05 g" in kilograms during your calculation and make sure your calculator is set to "degrees"). g = 9.8 m/s, and k = 8.99 x 109 N. m C2 one decimal place. Your answer should be of Pith Ball Mass 0.05 grams Charge on Each Ball
