Two lightweight balls hang straight down when both are neutral. They are close enough together to interact but not close enough to touch. 1D. Both balls are charged with a rubber rod that was rubbed with fur, but ball 1 is charged more than ball 2 . How does the magnitude of the electric force on Ball 1 compare to the magnitude of the electric force on Ball 2? The magnitude of the electric force on Ball 1 is smaller than the magnitude of the electric force on Ball 2 becasue Ball 1 with more charges repels Ball 2 harder. The magnitude of the electric force on Ball 1 is equal to the magnitude of the electric force on Ball 2. The magnitude of the electric force on Ball 1 is larger than the magnitude of the electric force on Ball 2 becasue Ball 1 has more charges.
