A tube of length LL is filled completely with an incompressible liquid of mass MM and closed at both the ends. The tube is then rotated in a horizontal plane about one of its ends with a uniform angular velocity ω\omega. The force exerted by the liquid at the other end is:

Options

  1. AML2ω22\frac{M L^2 \omega^2}{2}
  2. BMLω22\frac{M L \omega^2}{2}
  3. CML2ω2\frac{M L^2 \omega}{2}
  4. DMLω2M L \omega^2

Correct answer

B. MLω22\frac{M L \omega^2}{2}

Step-by-step solution

∴\therefore Centrifugal force =Mω2r=M \omega^2 r=M(12)ω2=MLω22.\begin{aligned}& =M\left(\frac{1}{2}\right) \omega^2 \\ & =\frac{M L \omega^2}{2} . \end{aligned}$$
