grain is pored into a silo to be stored for later use. due to the friction between pieces of grain as they rub against eachother during the pouring process, one piece of grain picks up a charge of 6.0e-10c and another piece of grain picks up a charge of 2.3e-15c. what is the electric force between them if the pieces are 2 cm apart?
