Kinematics Question 732
Question: Two masses and are attached to a vertical axis by weightless threads of combined length . They are set in rotational motion in a horizontal plane about this axis with constant angular velocity . If the tensions in the threads are the same during motion, the distance of from the axis it’s [MP PET 1995]
Options:

B)
C)
D)
Show Answer
Answer:
Correct Answer: B
Solution:
If the both mass are revolving about the axis yy’ and tension in both the threads are equal then
therefore
therefore
