1. [-/2 Points] DETAILS SERPSE10 22.1.OP.001. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER (a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 11.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are added for every 10 electrons already present? Need Help? Read It Watch It 2. [-/4 Points] DETAILS SERPSE10 22.3.OP.004. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER (a) Two protons in a molecule are 3.60 x 10-10 m apart. Find the electric force exerted by one proton on the other. magnitude N direction ---Select--- (b) State how the magnitude of this force compares with the magnitude of the gravitational force exerted by one proton on the other. Fe Fo c) What must be a particle's charge-to-mass ratio if the magnitude of the gravitational force between two of these particles is equal to the magnitude of electric force between them?
