Momentum and CollisionEasy
Question
A molecule of mass m of an ideal gas collides with the wall of the vessel with the velocity v and returns back with the same velocity. The change in the liner momentum of the molecule will be :
Options
A.4mv
B.8mv
C.2mv
D.-2mv
Solution
initial momentum = mv
final momentum = - mv
Change in the moment = mv - (-mv) = 2mv
final momentum = - mv
Change in the moment = mv - (-mv) = 2mv
