Two man of mass 50 kg and 60 kg on diametrically opposite point of a turntable of mass 90 kg. The turntable is free to rotate about vertical axis. The two men start moving towards each other along the circumference of table. The angle rotated by table when the two men meet each other –
Text Solution
Verified by ExpertsThe correct answer is:
B
Let ‘ θ ’ be angle rotated by turntable
Let mass of man 1 = m 1 (= 50 kg)
Let mass of man 2 = m 2 (= 60 kg)
Let mass of turntable = m (= 90 kg)
∴ m 1 (90 0 + θ ) + m 2 {– (90 0 – θ ) } + m. θ = 0
⇒ θ = 4.5 0
