Question
Two block A and B of equal mass m are connected through a mass less string and arranged as show in figure. Friction is absent everywhere. When the system is released from rest.
Options
A.tension in string is 
B.tension in string is 
C.acceleration of A is 
D.acceleration of A is 
Solution
Let acceleration of blocks ′s′ then
T + mg sin 30o = ma, mg - T = ma
⇒ a =
T = 
T + mg sin 30o = ma, mg - T = ma
⇒ a =
T = Create a free account to view solution
