Question

( related to spring constant)
explain please.

Answer 1

hii dear here is your answer hope it helps you...

:-)

Answer 2

let the length of spring be L

spring constant =K
if it cut into two parts 1:2 
so length of small part is L/3 and of large part is 2L/3 

let assume that ,spring constant of larger part is X 
 
as we know 
K ∝ 1/L------1
then 
X ∝ 1/(2L/3)-----2

after dividing both equation
K/X = 2/3
so 
X = 3K/2

i hope it will help you regards
