Ruth sets out to visit her friend Ward, who lives 50miles north and 100 miles east of her. She starts by driving east, but after 70 miles she comes to a detour that takes her 15miles south before going east again. She then drives east for 8 miles and runs out of gas, so Ward flies there in his small plane to get her. What is Ward’s displacement vector? Give your answer in component form, using a coordinate system in which the y-axis points north. What is the magnitude of Ward’s displacement vector? What is the direction of Ward’s displacement vector, measured clockwise from the negative y axis?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
