A pendulum having a bob of mass mm is hanging in a ship sailing along the equator form east to west. When the strip is stationary with respect to water, the tension in the string is T0T_0. The difference between T0T_0 and earth attraction on the bob, is

Options

  1. Amg+mω2R2\frac{m g+m \omega^2 R}{2}
  2. Bmω2R3\frac{m \omega^2 R}{3}
  3. Cmω2R2\frac{m \omega^2 R}{2}
  4. Dmω2Rm \omega^2 R

Correct answer

D. mω2Rm \omega^2 R

Step-by-step solution

Speed of ship due to rotation of the earth v=ωRv=\omega R The net force T0=mg−mω2R⇒T0−mg=mω2R\begin{aligned} T_0 & =m g-m \omega^2 R \\ \Rightarrow \quad T_0-m g & =m \omega^2 R\end{aligned}
