Two bodies of masses M and m are allowed...

Two bodies of masses M and m are allowed to fall from the same height. If air resistance for each body be same, will the two bodies reach the ground simultaneously ?

Text Solution

Verified by Experts

No the heavier body will reach the ground earlier . This is because , net downward force on body of mass `M = (Mg - F )` . Thereforce , its acc, ` a = (Mg - F )/(M) = g - (F)/(m)`
As `M gt m :. A gt a'` Heavier body will reach the ground earlier than the lighter body .

Assertion: Two bodies of masses M and m(M gt m) are allowed to fall from the same height if the air resistance for each be the same then both the bodies will reach the earth simultaneously. Reason: For same air resistance, acceleration of both the bodies will be same.

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.
