Gravitation Question 35
Question: If radius of the earth contracts 2% and its mass remains the same, then weight of the body at the earth surface [CPMT 1997; KCET (Engg./Med.) 2001]
Options:
A) Will decrease
B) Will increase
C) Will remain the same
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ [g\propto \frac{1}{R^{2}}] $ .
If radius of earth decreases by 2% then g will increase by 4% i.e. weight of the body at earth surface will increase by 4%
