Question

What do you mean by radius of gyration of a body ? Write dimensions of radius of gyration.

Answer 1

Answer:

Radius of gyration is length, so it has dimension of length i.e.$M^{o}LT^o$

Explanation:

When we apply tangential force on a body, if it is possible for body, the body will start rotating along a given axis. That axis will pass through the center of mass at which mass of the whole body is assumed to be concentrated, so the distance from that axis. Meter is used as the S.I unit of the radius of gyration.

The radius of gyration will have dimension of length i.e$M^{o}LT^o$

Answer 2

Explanation:

The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object's centers. Altering the separation distance (r) results in an alteration in the force of gravity acting between the objects.
