Alicia is asked to calculate the change in momentum that occurs as she stops her bicycle. this is equivalent to applied to the bicycle for a certain amount of time.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
