  • A$r\rho gh + mg$
  • B$r \rho gh - mg$
  • C$\pi r^2\rho gh + mg$
  • D$\pi r^2\rho gh - mg$

    A flat plate moves normally with a speed ${v_1}$ towards a horizontal jet of water of uniform area of cross-section. The jet discharges water at the rate of volume $V$ per second at a speed of ${v_2}$. The density of water is $\rho $. Assume that water splashes along the surface of the plate at right angles to the original motion. The magnitude of the force acting on the plate due to the jet of water is

    A $0.5\ kg$ mass of lead is submerged in a container filled to the brim with water and a block of wood floats on top. The lead mass is slowly lifted from the container by a thin wire and as it emerges into air the level of the water in the container drops a bit. The lead mass is now placed on the block of wood. As the lead is placed on the wood.
