From a tower of height \( H \), a particle is thrown vertically upwards with a speed \( u \). The time taken by the particle, to hit the ground, is \( n \) times that taken by it to reach the highest point of its path. The relation between \( H, u \) and \( n \) is:
(1) \( 2 g H=n u^{2}(n-2) \)
(2) \( g H=(n-2) u^{2} \)
(3) \( 2 g H=n^{2} u^{2} \)
(4) \( g H=(n-2) 2 u^{2} \)
