Questions
Consider the three cases given in figures shown. Assume the friction to be absent everywhere and the pulleys to be light; the string connecting the blocks to other block or flxed vertical wall to be light and inextensible . Let be the tension in the strings in figure A, figure B and figure C respectively. Then pick the correct comparison between the given tensions (for the instant shown) from options below.
detailed solution
Correct option is B
TA =2kgf.TB=Total forcetotal mass×Horizontally moving mass=2(1+2)×1=23kgf.Similarly TC=1(2+1)×2=23kgf.Hence TB=TCTalk to our academic expert!
