A ball 
of mass M moving northwards with velocity v collides elastically with another ball 
of same mass but moving eastwards with the same velocity v. Which of the following statements will be true
A
comes to rest but 
moves with velocity 
B
moves with velocity 
but 
comes to rest
C
Both move with velocity 
in north east direction
in north east direction
D
moves eastwards and 
moves north wards
Text Solution
Verified by ExpertsThe correct answer is:
D
Horizontal momentum and vertical momentum both should remain conserve before and after collision. This is possible only for the option.
