A bob of heavy mass m is suspended by a light string of length l. The bob is given a horizontal velocity v₀ as shown in figure. If the string gets slack at some point P making an angle θ from the horizontal, the ratio of the speed v of the bob at point P to its initial speed v₀ is:
A
(sin θ)¹ᐟ²
B
(1/(2 + 3 sin θ))¹ᐟ²
C
(cos θ/(2 + 3 sin θ))¹ᐟ²
D
(sin θ/(2 + 3 sin θ))¹ᐟ²
