If a spring of force constant 'K' is cut into three equal parts then the force constant of each part will be - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

$Force of spring is F = Kx$

$Force is constant Kx = constant, K is force constant Kl = constant, where l = length of the spring - - - - (1)$

$if length = \frac{l}{3}, then new force constant is k^{'}, K^{'} \frac{l}{3} = constant - - - - - - (2) K' \frac{l}{3} =Kl \Rightarrow K^{'} = 3 K$
