1 Laws of Motion
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
1)T=70.8N and T′=47.2N 2)T=58.8N and T′=47.2N 3)T=70.8N and T′=58.8N 4)T=70.8N and T′=0
SOLUTION:
T−T′−20=4 .............(i)
T′−40=8...................(ii)
By solving (i) and (ii)
T′=47.23N
and
T=70.8N
