Q
Two objects of masses m1 and m2 having the same size are dropped simultaneously from heights h1 and h2 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.
A
h1 = 1 gt21
2
h2 = 1 gt22
2
as x = o
𝑡1= √ℎ1
𝑡2 ℎ2
As the acceleration remain same ratio between two objects remain same. In this case acceleration does not depend upon mass and size.
