The centre of gravity of a uniform ring is situated at
The geometric centre of the ring
The geometric circumference of the ring
The mid –point of radius of the ring
The edge of the ring
The centre of gravity of a circular ring is at the geometric centre of the ring
In the given diagram, name the point(s)
a) In the interior of ∠DOE
(b) In the exterior of ∠EOF
(c) On ∠EOF
Mass of a ring is non-uniformly distributed around its geometric centre. If
R is radius of the ring, then
a. centre of mass does not coincide with geometric centre
b. Position centre of mass from the geometric centre will be x (0<x<R)
c. centre of mass will be nearer to the greater mass distribution
d. centre of mass may lie outside the periphery
