A
can be both positive and negative
B
can be zero depending on its position in the track
C
can be zero depending on its position in the track
D
a centrifugal
Ask EduPadi AI for a detailed answer
Correct Option: C
The angular momentum of an object moving in a circle with radius (r) is the product of the mass (m), velocity or speed of rotation (v), and the radius (r) of the circle.
At the centre where r = 0, the angular momentum is zero
