Class 11PhysicsNewton's Laws of Motion and FrictionMotion of Body (or Connected Bodies in horizontal or vertical) (by String or Contact)
Easy$A$ block $A$ of mass $7 \, kg$ is placed on a frictionless table. $A$ thread tied to it passes over a frictionless pulley and carries a body $B$ of mass $3 \, kg$ at the other end. The acceleration of the system is .......... $m \, s^{-2}$ (given $g = 10 \, m \, s^{-2}$).
- A$1$
- B$3$
