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.
C
Horizontal and intersecting the axis.
D
None of these.

✓

Answer

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.
