All pulley shown in figure are light and there is no friction between pulley and string. Acceleration of pulley 'P' in figure is given by –
Text Solution
Verified by ExpertsThe correct answer is:
D
Let acceleration of block A and B be a 1 and a 2 respectively and a p be acceleration of pulley P.
Let tension in string be T
According to principle of virtual work
3T. a p = T. a 1 + 8T a 2
a p = 
(upwards)
