The correct statement with regard to H+2 & H−2 is
Two block of wood of masses m1and m2 and each of specific gravity 0.5 are submerged at a depth of h1 and h2 in a vessel (h2>h1) filled with water, which is accelerated upwards with an acceleration g2. the difference in time taken by the blocks to reach the surface, when released with zero velocity is :
