A particle moving in a circle of radius R with a uniform speed takes a time T to complete
one revolution. If this particle were projected with the same speed at an angle 
to the horizontal, the maximum height attained by it equals 4R. The angle of projection 
is then given by [NEET 2021]
A
. B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Maximum height attained it is given as
… (i)
(given)
Also, we know that, speed of the particle in circular path,
Substituting the values in the Eq. (i), we get
