Q.
Three equal weights of 3kg each are hanging on a string passing over a frictionless pulley as shown in figure. The tension in the string between masses II and III will be (Take g=10m/sec2 )
Three equal weights of 3kg each are hanging on a string passing over a pulley as shown in figure.
If a is the common acceleration. T−3g=3a (For mass I) 3g+T1−T=3a (For mass II) 3g−T1=3a (For mass III)
Adding, above three equations 3g=9a,a=g/3 T1=3g−3a=3g−g=2g=20N
