A) 2.38
B) 4.68
C) 5.98
D) 6.38
Correct Answer: D
Solution :
Centripetal acceleration \[\operatorname{a} = \frac{{{v}^{2}}}{r}\] \[=\,\,\frac{{{(250)}^{2}}}{1000}\,\,[as,\,900km/h=250m/s]\] Now, \[\frac{a}{g}=\frac{{{(250)}^{2}}}{1000}\times \frac{1}{9.8}=6.38\]You need to login to perform this action.
