Spring\;Constant (k)\; \alpha\;\frac{1}{length\; of\; the\; spring\;(l)}

as length becomes half, k becomes twice i.e 2k

 

Time period of oscillation for spring mass system -

T= 2\pi \sqrt{\frac{m}{K}}

- wherein

m = mass of block

K = spring constant

k

This is incorrect.

Option 3)

2k

This is correct.
