You need to raise a heavy block by pulling it with a massless rope. You can either (a) pull the block straight up height h, or (b) pull it up a long, frictionless plane inclined at a 15∘ angle until its height has increased by h.

A 320-m length of wire stretches between two towers and carries a 120-a current. determine the magnitude of the force on the wire due to the earth's magnetic field of 5.0 * 10-5t which makes an angle of 60 ∘ with the wire.
