An elastic spring under tension of 3 N has a length a . Its length is b under tension 2 N . For its length ( 3 a − 2 b ) , the value of tension will be______ N .

Question

TestHub · Accepted Answer

​ 3 = K ( a − ℓ ) 2 = K ( b − ℓ ) T = K ( 3 a − 2 b − ℓ ) T = K ( 3 ( a − ℓ ) − 2 ( b − ℓ ) = K [ 3 ( K 3 ​ ) − 2 ( K 2 ​ ) ] = 9 − 4 = 5 N ​
