when a bucket of water is pulled out using a rope which is running on a pulley,what is the direction of the pull of the person?Is it against or in the direction of gravitational force?
Dear Student!!
No the direction the pull of the person is not against the gravity but it is along the tangent to the circular pulley. When he pulls the rope tension produces in the rope, this tension in the rope is responsible for the upward motion of the bucket.
