Electric charges surround you all the time. Some electric charges, such as lightning, are quite strong. Others are barely noticeable. What happens when two electrically charged obiects get near each other? Circle the response that best matches your thinking I’ll give brainlest:^^

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
