Q23 of 61 Page 318

Two bodies, one held 1 m vertically above the other, are released simultaneously and fall freely under gravity. After 2 second, the relative separation of the bodies will be:

Now, initial separation = 1 m


Body 1:


Initial Speed = 0


Acceleration = 9.8 ms-2


Time = 2 seconds


Now, we know that,



So,


m


Body 2:


Initial Speed = 0


Acceleration = 9.8 ms-2


Time = 2 seconds


Now, we know that,



So,


m


Since, so final separation is also 1 m.


Hence, option D is correct.
