Question

Two masses $A$ and $B$, each of mass $M$ are fixed together by a massless spring. $A$ force acts on the mass $B$ as shown in figure. If the mass $A$ starts moving away from mass $B$ with acceleration ' $a$ ', then the acceleration of mass $B$ wil be :-

Select the correct option:

A

$\frac{\mathrm{Ma}-\mathrm{F}}{\mathrm{M}}$

B

$\frac{M F}{F+M a}$

C

$\frac{F+M a}{M}$

D

$\frac{F-M a}{M}$

✓ Correct! Well done.
