    Figure shows a siphon. The liquid shown is water. The pressure difference PB - PA between the points A and B is
    (a) 400 Nm-2
    (b) 3000 Nm-2
    (c) 1000 Nm-2
    (d) zero

    Ans : (d) zero
    At both points A and B, pressure is equal to atmospheric pressure.
    `` \,\mathrm{\,Thus\,},\,\mathrm{\,we\,}\,\mathrm{\,have\,}:``
    `` {P}_{\,\mathrm{\,A\,}}={P}_{\,\mathrm{\,B\,}}={P}_{\,\mathrm{\,atm\,}}``
    `` \Rightarrow {P}_{\,\mathrm{\,B\,}}-{P}_{\,\mathrm{\,A\,}}=0``
