Answer» tension in the string be T....now,when,the block will move upward then there will be a pseudo ACCLERATION which will be just opposite to the acceleration of the whole block...so,total force ACTING downward on first =2G+2g/2total force acting upward on second block=4g+4g/2now,if mass of 4g is acelrating downward than(4g+2g)-T=4×a6g-T=4a.......i) for second block..T-(2g +2g/2)=2at-3g=2a.....ii)adding both we get3g=6ag=2aa=g/2putting this value of a in ii) we gett=2×g/2+3gt=g+3gT=4g=40Hence tension in the string will be 40NHence OPTION a)✓✓✓hope it HELPS you |
