A) \[\frac{w}{2}\]
B) \[\frac{2w}{3}\]
C) \[\frac{4w}{9}\]
D) \[\frac{8w}{27}\]
Correct Answer: C
Solution :
The value of acceleration due to gravity at a height \[h\]above the earths surface is given by \[g=\frac{g}{{{\left( 1+\frac{h}{R} \right)}^{2}}}\] Where R is radius of earth. When \[h=\frac{R}{2}\] \[g=\frac{g}{{{\left( 1+\frac{1}{2} \right)}^{2}}}\] \[=\frac{4g}{9}\] Hence, weight \[w=mg=\frac{4}{9}mg=\frac{4}{9}w.\]You need to login to perform this action.
