A) 3 \[mn\upsilon \]
B) \[mn\upsilon \]
C) \[2mn\upsilon \]
D) none
Correct Answer: C
Solution :
Pressure = change in momentum change in momentum for a ball \[=m\upsilon -(-m\upsilon )=2m\upsilon \] Therefore, for n balls change in momentum \[=2mn\upsilon \]You need to login to perform this action.
