Question

A uniform spring of normal length l has a force constant k . It is cut into two pieces of length l 1 and l 2 such that l 1 = n l 2 where n is an integer. Then the value of k 1 (force constant of spring of length l 1 ) is-, k n n + 1, k n + 1 n, k n - 1 n, k n n - 1

MARKS App · Accepted Answer

Using the relation kx = constant k 1 l 1 = k 2 l 2 = k l 1 + l 2 k 1 = k l 1 + l 2 l 1 or k 1 = k n l 2 + l 2 n l 2 or k 1 = k n + 1 n
