The upper block is hung by another string. A force F applied on the upper string produces an acceleration of 2m/s2 in the upward direction in both the blocks. If T and T’ be the tensions in the two parts of the string, then:

Two blocks are connected by a string as shown in the diagram. The upper block is hung by another string. A force F applied on the upper string produces an acceleration of 2m/s2 in the upward direction in both the blocks. If T and T’ be the tensions in the two parts of the string, then:

A force f1​ acts on a particle so as to accelerate it from rest to a velocity v. If the force f1​ is replaced by f2​ which decelerates it to rest
