The massless string connecting slider A and mass B passes over two small massless smooth pulley, one which is attached to 'A'. The end of strings are attached to mass B and roof as shown. Mass B has constant velocity V 0 directed downwards. At the instant when Y A = b, the magnitude of acceleration of A is –
A
B
C
D
None
Text Solution
Verified by ExpertsThe correct answer is:
C
2V A cos θ = V 0 ⇒ 2a A cos θ – 2V A sin θ 
= 0
Y A = b cot θ
⇒ V A = b cosec 2 θ 
∴ a A =
