A satellite has kinetic energy \(K\), potential energy \(V\) and total energy \(E .\) Which of the following statements is true?
- A \(K=-V / 2\)
- B \(K=V / 2\)
- C \(E=K / 2\)
- D \(E=-K / 2\)
Answer & Solution
Correct Answer
(A) \(K=-V / 2\)
Step-by-step Solution
Detailed explanation
As we know that for the earth and satellite system Kinetic energy, \(\quad K=\frac{G M m}{2 a}\) Potential energy, \(V=-\frac{G M m}{a}\) and total energy, \(E=-\frac{G M m}{2 a}\) where, \(a=\) radius of the orbit of the satellite and \(m=\) mass of the satellite On the basis…

WBJEE 2018 Easy - A bar of length L carrying a small mass \(m\) at one of its ends rotates with a uniform angular speed \(\omega\) in a vertical plane about the mid point of the bar. During the rotation, at some instant of time when the bar is horizontal, the mass is detached from the bar but the bar continues to rotate with some \(\omega .\) The mass moves vertically up, comes back and reaches the bar at the same point. At that place, the acceleration due to gravity is \(g\)WBJEE 2013 Medium
