A) \[50\hat{i}-1.5\hat{j}\text{ m/}{{\text{s}}^{2}}\]
B) \[-50\hat{i}-1.5\hat{j}\text{ m/}{{\text{s}}^{2}}\]
C) \[10\hat{i}-1.5\hat{j}\text{ m/}{{\text{s}}^{2}}\]
D) \[1.5\hat{i}-50\hat{j}\text{ m/}{{\text{s}}^{2}}\]
Correct Answer: B
Solution :
[b] Centripetal acceleration \[{{a}_{n}}=\frac{{{v}^{2}}}{r}=\frac{{{10}^{2}}}{2}=50m/{{s}^{2}}\], along negative x-axis. so \[\overrightarrow{a}=-50\hat{i}-1.5\hat{j}m/{{s}^{2}}\]
