Question
A frictionless track 
ends in a circular loop of radius 
figure. A body slides down the track from point 
which is at a height 
cm. Maximum value of 
for the body to successfully complete the loop is
- 5 cm
- 15/4 cm
- 10/3 cm
- 2 cm
The correct answer is: 2 cm
For successfully completing the loop,
