Physics Two Dimensional Motion Question 87
Question: A body slides down a frictionless track which ends in a circular loop of diameter $ D $ , then the minimum height $ h $ of the body in term of $ D $ so that it may just complete the loop, is
Options:
A) $ h=\frac{5D}{2} $ B)$ h=\frac{5D}{4} $ C) $ h=\frac{3D}{4} $ D) $ h=\frac{D}{4} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ h=\frac{5}{2}R=\frac{5}{2}( \frac{D}{2} )=\frac{5D}{4} $
