She pulls upward with a force P. The weight of the crate is W, and the normal force from the floor is . How are the magnitudes of these forces related? A) P=n B) P+n<W C) P+n=W D) P+n> W E) n = W 5) An object with mass 7.7 kg is pulled on a horizontal surface by a 50.0 N horizontal force to the right.
