hey friends i 've a doubt in HCV Newton laws of motion in "Questions for short answers" section...... i m sorry but image uploading is not working on the system....
Q. no. 8; fig 5-Q1
th equestion is the figure which is depicted ....... what will be the reading of the spring balance:.. plz refer the complete question from the book..............
71It shall be 20 kg wt.
Mathematically, One the right side say the tension in the string is T and on the left side it is T'.
Since, they aren't accelerating. Therefore,
LHS: T = 20g
RHS: T'= 20g
But since the spring balance in the middle is assumed to be massless, and hence the tension in all the parts of it would be uniform and equal (If we consider force pairs)
i.e., T = T' = 20 kg wt
1thanks vivek....bt wht will be the reading of the spring bal.....
this was nt full sol.... i think there were sum more of it.....
71Sum more.
TRY ZOOMING AND READ CALMLY. I hope it is readable.
