In the table shown below, column-II shows the possible outcomes to the water level of a swimming pool when a person standing on a boat in it does any one of the actions shown in column-I
Column-I | Column-II | ||
i. | He throws a 20 kg iron anchor from the boat into the water, which then settles at the bottom () | p. | It becomes lower |
ii. | He throws out a 20 kg log of wood from the boat. The log floats on water () | q. | It becomes higher |
iii. | He empties 20 kg of water from the boat into the pool. | r. | It says the same |
iv. | He drinks some water from the pool. | s. | Cannot be predicted from the information given |
Now match the given columns and select the correct option from the codes given below.
Codes
When iron is in boat, it will displace more volume of water than when it is directly in water.
A log of wood will float in both cases, hence it will displace same amount of water in both cases. No effect on level of water, if water is transferred either from boat into pool or from pool to boat.
