Answer ( 1 )

  1. As the block is inside the water, so definitely there will be some water displaced by that block.
    So there will be some buoyancy force on that block which will be equal to the weight of water displaced by the block.
    Also, volume of water displaced by block = volume of the block = v

    Considering the density of water as 1000 Kg/m^3 and let us assume the volume given to be in m^3
    so, buoyancy force = volume * density = v*1000 = 1000v
