A particle is thrown upwards from ground. It experiences a constant resistance force which can produce retardation \( 2 \mathrm{~m} / \mathrm{s}^{2} \). The ratio of time of ascent to the time of descent is \( \left[g=10 \mathrm{~m} / \mathrm{s}^{2}\right] \)
(a) \( 1: 1 \)
(b) \( \sqrt{\frac{2}{3}} \)
(c) \( \frac{2}{3} \)
(d) \( \sqrt{\frac{3}{2}} \)
