MCQ
A body is rotating uniformly about a vertical axis fixed in an inertial frame. The resultant force on a particle of the body not on the axis is:
  • A
    Vertical.
  • B
    Horizontal and skew with the axis.
  • ✓
    Horizontal and intersecting the axis.
  • D
    None of these.
✓

Answer

Correct option: C.
Horizontal and intersecting the axis.
Explanation:

Because resultant force on a particle of the body rotating uniformly is always perpendicular to the rotation axis and pass through it.
