The length of an elastic string is a metre when the longitudinal tension is 4N and b metre when the tension is 5 N . The length of the string (in meter), when the longitudinal tension is 9 N is :-

Options:

Answer:

Solution:

If L is initial length mass

$a = L + \frac{4 L}{π r ^{2} y} b = L + \frac{5 L}{π r ^{2} y}$

Then $x = L + \frac{9 L}{π r ^{2} y}$ From (i), (ii) and (iii) $x = 5 b - 4 a$
