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.

To solve the problem, we will follow these steps: ### Step 1: Understand the problem We have two objects with masses \( m_1 \) and \( m_2 \) that are dropped from heights \( h_1 \) and \( h_2 \) respectively. We need to find the ratio of the time taken by each object to reach the ground. ### Step 2: Use the equations of motion We will use the second equation of motion, which states: \[ ...
