Five particles of mass \( 2 \mathrm{~kg} \) each are attached to the circumference of circular
\( \mathrm{P} \) disc of a radius \( 0.1 \mathrm{~m} \) and negligible mass.
\( \mathrm{W} \) Moment of inertia of the system about the axis passing through the centre of disc and perpendicular to its plane is
(1) \( 1 \mathrm{~kg} \mathrm{~m}^{2} \)
(2) \( 0.1 \mathrm{~kg} \mathrm{~m}^{2} \)
(3) \( 2 \mathrm{~kg} \mathrm{~m}^{2} \)
(4) \( 0.2 \mathrm{~kg} \mathrm{~m}^{2} \)
