A homogeneous disc of mass 2 kg and radius 15 cm is rotating about its axis (which is fixed) with an angular velocity of 4 radian/sec. The linear momentum of the disc is
A
1.2 kg m/sec
B
1.0 kg m/sec
C
0.6 kg m/sec
D
None of the above
Answer
None of the above
Explanation
Solution
Since axis of the disc is fixed therefore velocity of centre of mass is zero.
