Question

Consider the following the equations
(A) \[\vec{R} = \frac{1}{M} \sum_i m_i \vec{r_i}\] and
(B) \[\vec{a}_{CM} = \frac{\vec{F}}{M}\] 
In a noninertial frame

पर्याय

• both are correct

• both are wrong

•  A is correct but B is wrong

•  B is correct but A is wrong.

Answer 1

 A is correct but B is wrong

In a non-inertial frame, the position of centre of mass of the particle does not change but an additional pseudo force acts on it.
