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