Answer :
D
Solution :
speed of the block at B,v=2gh−−−√
top complete the vertical circle, v≥5gR−−−−√

Answer:
- we can guess think of it as a normal pendulum..
- the length is not given
- at equilibrium if the tension is 2 mg=T
- where T must be =mg+mv^2/r
- so mv^2/r r=mg
- v=root of gr
- so y=asinwt
- v=awsinwt
