Problem

A spring whose unstretched length is

l

has a force constant

k

. The spring is cut into two pieces of unstretched lengths

l_1

and

l_2

where,

l_1 = nl_2

and

n

is an integer. The ratio

k_1/k_2

of the corresponding force constants,

k_1

and

k_2

will be: [12 April 2019 II] (a)

n

(b)

\frac{1}{n^2}

(c)

\frac{1}{n}

(d)

n^2
