Assertion : Two bodies of unequal masses...

Assertion : Two bodies of unequal masses `m_1 and m_2` are dropped from the same height. If the resistance offered by air to the motion of both bodies is the same, the bodies will reach the earth at the same time.
Reason : For equal air resistance, acceleration of fall of masses `m_1 and m_2` will be different.

A

If the both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D

`a=(mg-F)/m`
`=g-F/m`=depends on m
Since `m_1!=m_2`
`:. a_1!=a_2`
or `t_1!=t_2`
