Kinematics Question 489
Question: A particle it’s sliding down a frictionless hem it’spherical bowl. It passes the point at . At this instant of time, the horizontal component of it’s velocity is . A bead of the same mass as it’s ejected from at along the horizontal string with the speed . Friction between the bead and the string may be neglected. Let and be the respective time taken by and to reach the point . Then [IIT 1993]
Options:
A)
B)
C)
D) All of these
Show Answer
Answer:
Correct Answer: A
Solution:
For particle P, motion between A and C will be an accelerated one while between C and B a retarded one. But in any case horizontal component of it’s velocity will be greater than or equal to v on the other hand in case of particle Q, is always equal to v. horizontal displacement of both the particles are equal, so
