Gravitation Question 22
Question: The moon’s radius is 1/4 that of the earth and its mass is 1/80 times that of the earth. If g represents the acceleration due to gravity on the surface of the earth, that on the surface of the moon is [MP PMT 1997; MP PET 2000, 01; RPET 2000; Pb. PET 2001]
Options:
A) g/4
B) g/5
C) g/6
D) g/8
Show Answer
Answer:
Correct Answer: B
Solution:
Using $ [g=\frac{GM}{R^{2}}] $
we get $ [g_{m}=g/5] $
