Akash Anand I guess your answer is wrong. Better you specify it with direction. And remember string wont get lag. Upvote·0· Reply ·2013-02-13 22:59:19- Sourish Ghosh If tension exists, then is the answer 0, 0 ?
- Akash Anand Of-course tension will be there, and answer is not zero.
486The acc. of B is twice that of A as tension in the string connecting A is two times that of B .
SO, acc. of B=3 and of A=1.5
- Akash Anand In which direction A & B will move, and if your answer is correct then sting should lag.
Swarna Kamal Dhyawala A WOULD MOVE UPWARD WITH ACC OF 1.5 AND B WOULD MOVE DOWNWARDS WITH ACC OF 3 - Akash Anand @Swarna Kamal..you are wrong, according to your answer the leangth of the string going to increase with time.
- Swarna Kamal Dhyawala sir then what is the right answer
- Swarna Kamal Dhyawala i think A would move upward with 1.5 and B would move downward with 1.5
- Swarna Kamal Dhyawala no sorry A would move downward by 1.5 and B would move upward by 3
43B upward with 1.5 , A downward with 3...
- Soumyabrata Mondal Acc. of B suld be twice of A
1161The right answer will be .. Both block will move upward with the acceleration of 1 m/s2.
Now anyone give the solution. :)
- Soumyabrata Mondal hmm
any hint
- Akash Anand Tension in the string will be same,take acceleration of the block in any direction as you wish, write the constraint relation, & force balance equation and solve it. Try to be careful about the constraint relation.
36Let 5kg mass move by x, 10 kg mass by x' and truck by x" with account a,a',a" respectively
Tx+2Tx'=Tx" differentiating, and putting a" =3
a+2a'=3
By balancing F,
T-5g=5a
2T-10g=10a'
---> a-a'=0
a=1 and a'=1
- Akash Anand Good job :)
