A frictionless track ABCDE ends in a circular loop of radius R . A body slides down the track from point A which is at a height h = 5 cm . Maximum value of R for the body to successfully complete the loop is

A

5cm

B

`(15)/(4)` cm

C

`(10)/(3)` cm

D

2 cm

Text Solution

Verified by Experts

The correct Answer is:
D
Condition for vertical looping `h=(5)/(2)r = 5cm " " therefore r=2cm`
