Two dogs are pulling on a bone with one dog pulling with a force of 15 N due east and the other pulling with a force of 25 N due north. Determine the resultant vector and its angle that
is exerted on the bone by the dogs.

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.
