Q: 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 2 m/s2 in the upward direction in both the blocks. If T and T ‘ be the tensions in the two parts of the string, then (g = 9.8 m/s2)

Numerical

(a) T = 70.8 N and T ‘ = 47.2 N

(b)T = 58.8 N and T ‘ = 47.2 N

(c) T = 70.8 N and T ‘ = 58.8 N

(d)T = 70.8 N and T ‘ = 0
