Define 1-newton force.
Force is said to be 1 newton if it produces 1 ms−2 acceleration in a body of 1 kg.
(a) Define buoyant force. Name two factors on which buoyant force depends. (b) What is the cause of buoyant force ? (c) When a boat is partially immersed in water, it displaces 600 kg of water. How much is the buoyant force acting on the boat in newtons ? (g=10ms−2)
