In the figure, the wedge is pushed with an acceleration of \( 10 \sqrt{3} \mathrm{~m} / \mathrm{s}^{2} \). It is seen that the block starts climbing up on the smooth inclined face of wedge. What will be the time taken by the block to reach the top?
(a) \( \frac{2}{\sqrt{5}} \mathrm{~s} \)
(b) \( \frac{1}{\sqrt{5}} \mathrm{~s} \)
(c) \( \sqrt{5} \mathrm{~s} \)
(d) \( \frac{\sqrt{5}}{2} \mathrm{~s} \)
