Time period of pendulum, on a satellite orbiting the earth, is
Time period of pendulum, on a satellite orbiting the earth, is
Options
- A
- Bzero
- C
- Dinfinity
Correct answer
D. infinity
Step-by-step solution
On an artificial satellite orbiting the earth the acceleration is given by towards the centre of the earth. Now for a body of mass on the satellite the graviational force due to earth is towards the centre of the earth. Let the reaction force on the surface of the satellite be , then
\Rightarrow \quad N=0g=0
\therefore \quadT=2 \pi \sqrt{\frac{l}{g}}=\infty
