A conical pendulum of length $\displaystyle 1$ m makes an angle $\displaystyle \theta=45^{\circ}$ w.r.t. Z-axis and moves in a circle in the XY plane. The radius of the circle is $\displaystyle 0.4$ m and its center is vertically below O. The speed of the pendulum, in its circular path, will be : $\displaystyle \left(\right.$ Take $\displaystyle \left.\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$
Official answer
(4)
$\displaystyle 2$ m/s
