The change in value of g at the surface of a planet if its mass is doubled and radius is tripled.
Answer to Problem 38P
Solution:
The value of acceleration due to gravity changes near the surface of the hypothetical planet by a factor of
Explanation of Solution
Given:
The hypothetical planet of the mass is 2 times as that of the Earth = 2
Radius of the hypothetical planet =
Formula Used:
G is the gravitational constant and r is the distance of the point from the Earth where g is required to be found.
Calculation:
Conclusion:
Therefore, the value of acceleration due to gravity changes near the surface of the hypothetical planet by a factor of
