$straight A space recording space disc space rotates space steadily space at space 45 space rev divided by min space on space straight a space table. space When space straight a space small space mass space of space 0.02 space kg space is space dropped space gently space on space the space disc space at space straight a space distance space of space 0.04 space straight m space from space its space axis space and space stucks space to space the space disc comma space the space rate space of space revolution space falls space to space 36 space rev divided by min. space The space moment space of space inertia space of space the space disc space about space its space centre space is$

$1.28 \times 10^{- 4} kg - m^{2}$
$1.28 \times 10^{- 5} kg - m^{2}$
$1.28 \times 10^{- 3} kg - m^{2}$
$1.28 \times 10^{- 2} kg - m^{2}$

The correct answer is: $1.28 cross times 10 to the power of negative 4 end exponent space kg minus straight m squared$
