Q. The radius of gyration is defined as the distance from the axis of rotation to a point where?

परिभ्रमण की त्रिज्या को घूर्णन अक्ष से उस बिंदु तक की दूरी के रूप में परिभाषित किया जाता है जहां?

A
The entire mass of the body can be assumed to be concentrated
शरीर का संपूर्ण द्रव्यमान संकेंद्रित माना जा सकता है
B
The torque is maximum
टॉर्क अधिकतम है
C
The angular velocity is maximum
कोणीय वेग अधिकतम होता है
D
The linear velocity is zero
रैखिक वेग शून्य है

Explanation

The radius of gyration kk is defined by:

I=Mk2I = Mk^2

It is the distance from the axis of rotation at which the whole mass MM can be considered to be concentrated to give the same moment of inertia II.
