The field from a large plate a is 1180 n/c pointing eastward, while another plate b produces a field that is 1520 n/c northward. what is the net field produced by the combination?
? n/c
an object has been charged to 480 μc and placed in the field.
what is the magnitude of the force on the object?
? n

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
