Two objects of massses `m_(1)` and `m_(2)` having the same size are dropped simultaneously from hights `h_(1) and h_(2)` respectively. Find out the ratio of time they would take in reaching the ground. Will this ratio remain the same if (i)one of the objects is hollow and the other one is solid and (ii)both of them are hollow, size remaining the same in each case. give reason.
