MCQ

A spring having a spring constant $~ K$ ' is loaded with a mass ' $m$ '. The spring is cut into two equal parts and one of these is loaded again with the same mass. The new spring constant is

A
$K / 2$
B
$K$
✓
$2 K$
D
$K^2$

✓

Answer

Correct option: C.

$2 K$

(c) Spring constant $(k) \propto \frac{1}{\text { Lengthofthe } \operatorname{spirng}(l)}$ as length becomes half, $k$ becomes twice is $2 k$.
