Physics - NLM Question with Solution | TestHub

The acceleration of the system in rightward direction is

$a=\frac{F}{m_A+m_B+m_C}=\frac{F}{3M}$

For A

From force diagram of A, the Net force on A$=F-F_1$

$=m_{1}a=\frac{MF}{3M}=\frac{F}{3}$




The force interaction between A and B is$F_1=F-\frac{F}{3}=\frac{2F}{3}$
