Three massses is in contact as shown. If force F is applied to mass m1, the acceleration of three masses is –
A. \(\frac{\mathrm{F}}{m_{1}+m_{2}+m_{3}}\)
B. \(\frac{m_{1} F}{\left(m_{1}+m_{2}+m_{3}\right)}\)
C. \(\frac{\left(m_{2}+m_{3}\right) F}{\left(m_{1}+m_{2}+m_{3}\right)}\)
D. \(\frac{m_{3} \mathrm{F}}{m_{1}+m_{2}+m_{3}}\)
