Question
A wooden block of mass m and density d is tied to a string, the other end of the string is fixed to the bottom of a tank. The tank is filled with a liquid of density 
. What is the tension in the string
The correct answer is:
This is the upward force on the block due to buoyancy.
The downward force on the block = its weight = m g
