A) \[\text{34}0\text{ cm}/{{\text{s}}^{\text{2}}}\]
B) \[\text{34 cm}/{{\text{s}}^{\text{2}}}\]
C) \[\text{3}.\text{4 cm}/{{\text{s}}^{\text{2}}}\]
D) \[0.\text{34 cm}/{{\text{s}}^{\text{2}}}\]
Correct Answer: C
Solution :
\[a={{\omega }^{2}}R={{\left( \frac{2\pi }{T} \right)}^{2}}\times R\] \[={{\left( \frac{2\times 22}{7\times 24\times 3600} \right)}^{2}}6400\] \[=3.4\times {{10}^{-2}}m/{{s}^{2}}=\mathbf{3}\mathbf{.4}\,\,\mathbf{cm/}{{\mathbf{s}}^{\mathbf{2}}}\]
