A mass of $\displaystyle 0.5$ kg is attached to one end of a massless spring whose natural length is $\displaystyle 1$ m and spring constant is $\displaystyle 800 \mathrm{~N} / \mathrm{m}$ The other end of the spring is fixed while the mass moves in a circular path in a horizontal plane with an angular speed of $\displaystyle 20$ rad/s. The extension in the length of the spring will be :
Official answer
(3)
$\displaystyle \frac{1}{3} \mathrm{~m}$
