A stone dropped from a building of height \( h \) and it reaches after \( t \) seconds on earth. From the same building if two stones are thrown (one upwards and other downwards) with the same velocity \( u \) and they reach the earth surface after \( t_{1} \& t_{2} \) seconds respectively, then [CPMT 1997; UPSEAT 2002; KCET 2002]
(a) \( t=t_{1}-t_{2} \)
(b) \( t=\frac{t_{1}+t_{2}}{2} \)
(c) \( t=\sqrt{t_{1} t_{2}} \)
(d) \( t=t_{1}^{2} t_{2}^{2} \)
