361023 The force of buoyancy is equal to

361024 Assertion :
Taking into account the fact that any object which floats must have an average density less than that of water, during world war \(I\), a number of cargo vessels were made of concrete.
Reason :
Concrete cargo vessels were filled with air.

361025 A small block of wood of relative density 0.5 is submerged in water. When the block is released, it starts moving upwards, the acceleration of the block is \(\left( {g = 10\;m{s^{ - 2}}} \right)\)

361026 A wooden block of mass \(8\;kg\) is tied to a string attached to the bottom of the tank. In the equilibrium the block is completely immersed in water. If relative density of wood is 0.8 and \(g = \) \(10\;m{s^{ - 2}}\), the tension \(T\), in the string is
