Question

A man first swims in sea water and then in river water. Where does he find it easier to swim ?

• A. Sea water
• B. River water
• C. Same in both
• D. None of the above

Answer 1

The correct option is A Sea water

In sea water because the density of sea water is more than that of river water so his weight is balanced in sea water with his less part submerged inside it.
Since, the density of sea water is more, upthrust will be more in case of sea water and therefore it will easier for a man to swim in sea water as the upthrust would push him up.
