Question

Consider the following the equations
(A) →R=1M∑imi→ri
and
(B) →aCM=→FM
In a noninertial frame
(a) both are correct
(b) both are wrong
(c) A is correct but B is wrong
(d) B is correct but A is wrong.

Answer 1

(c) A is correct but B is wrong.

Explanation:

The location of the particle's center mass does not shift in a non-inertial frame, but an external pseudo force acts on it.

Center of mass:-  

Center of mass is stated as a fixed location relative to an object or a group of objects. It is the average location of all elements of the system, weighted by their masses. The center of the mass is found in the centroid, for simple rigid structures of uniform density.
