A man is sitting in a boat which is floating in a pond. If the man drinks some water from the pond, what will happen to the level of water in the pond?

Answer»

Solution :If the mandrinks m gram of water from thepond, te WEIGHT of (boat + MAN) system will increase by mg and so the system will displace m gram more water for floating. So due ot removal FO water from pond, the water level in pond will fall but due to water displaced by the floating system the water level in the pond will rise and so the water REMOVED FORM the pond is equal to the water displaced by the system, the level of water in the pond will remain unchanged.
