A) decrease by 1%
B) remain unchanged
C) increase by 1%
D) increase by 2%
Correct Answer: D
Solution :
Acceleration due to gravity \[g=\frac{GM}{{{R}^{2}}}\] So, by power law for errors \[\frac{\Delta g}{g}=-\frac{2\Delta R}{R}\] Thus, 1% decrease in radius of earth will result in 2% increase in acceleration due to gravity.You need to login to perform this action.
