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

Question

Accepted Answer

Correct answer: 5. (5) 3=K (a-l ) 2=K (b-l ) T=K (3a-2 b-l ) T=K (3 (a-l )-2 ( b-l ) =K(3 ( 3 K )-2 ( 2 K )) =9-4 =5 N

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