[AIPMT 2001]
Options:
A) the velocity of point A is
B) the velocity of point A is zero and velocity of points is
C) the velocity of point A is
D) the velocities of both A and B w are
Show Answer
Answer:
Correct Answer: A
Solution:
-
Key Idea: For a body rolling without slipping, the velocity of any point P on the body is
where
Velocity of point A is,
Velocity of point B is,
Thus, the velocity of point A is
