A) 1 : 4
B) \[\frac{1}{4}:1\]
C) 2 : 1
D) 4 : 1
Correct Answer: D
Solution :
In a circular motion \[a=\frac{{{v}^{2}}}{r}\] \[\therefore \] \[\frac{{{a}_{2}}}{{{a}_{1}}}={{\left( \frac{{{v}_{2}}}{{{v}_{1}}} \right)}^{2}}\] \[={{\left( \frac{2{{v}_{1}}}{{{v}_{1}}} \right)}^{2}}=4\]You need to login to perform this action.
