A wooden block of mass 8 kg is tied to string attatched to the bottom of the tank.In equilibrium the block is completely immersed in water. if relative density of wood is 0.8 and g=10m/s^2 then what is the value of tension in the string

Best ResponseYou've already chosen the best response.1The net force on the block of wood is gravity minus the buoyant force. Gravity is straight forward. To find the buoyant force, you want to the weight of the displaced water; to find that, you'll need to calculate the volume of the block.

Best ResponseYou've already chosen the best response.0since wood, will float on water, tension in the string would be zero

Best ResponseYou've already chosen the best response.1On the contrary, because the block of wood is under the surface of the water, because the problem says it's tied to the bottom, the tension on the string must be something not equal to zero.
