A pendulum having a bob of mass m 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 T₀ . The difference between T₀ and earth attraction on the bob, is
Options
- Am g+m ^2 R 2
- Bm ^2 R 3
- Cm ^2 R 2
- Dm ^2 R
Correct answer
D. m ^2 R
Step-by-step solution
Speed of ship due to rotation of the earth v= R The net force aligned T₀ & =m g-m ^2 R T₀-m g & =m ^2 R aligned
