5.

The locus of the instantaneous centre of a moving rigid body, is

 [A]. straight line [B]. involute [C]. centroid [D]. spiral.

Explanation:

No answer description available for this question.

 Dhanush said: (Dec 25, 2016) Center of area of such plan figures is called centroid.

 Rc Phuyal said: (Mar 1, 2017) It is involute.

 Babagana said: (Jun 21, 2017) @Rc Phuyal. Can you explain it in detail? Please.

 Srikisna said: (Nov 5, 2017) No how could it be centroid. ? Question is asking about the locus and centroid is a point of plane figure while it is a mass body.

 Ganpat Suryabhan Shinde said: (Apr 26, 2018) Please explain it in detail.

 Twinkle Vinu said: (Apr 14, 2019) It is centrode not centroid.

 Pranita Dc said: (Aug 26, 2019) The answer is centrode. Centrode, in kinematics, is the path traced by the instantaneous center of rotation of a rigid plane figure moving in a plane. The Centroid is the average position of all the points of an object.
