Gravitation Question 256
Question: If Gravitational constant is decreasing in time, what will remain unchanged in case of a satellite orbiting around earth [DCE 1999, 2001]
Options:
A) Time period
B) Orbiting radius
C) Tangential velocity
D) Angular velocity
Show Answer
Answer:
Correct Answer: C
Solution:
$ [T^{2}=\frac{4{{\pi }^{2}}}{GM}r^{3}] $ .
If G is variable then time period, angular velocity and orbital radius also changes accordingly.
