The acceleration of the system shown in the figure is given by the expression (ignore force of friction)

A. \(\mathrm{a} = \frac{\mathrm{m}_2\mathrm{g}}{(\mathrm{m}_1 + \mathrm{m}_2)}\)

B. \(\mathrm{a} = \frac{\mathrm{m}_1\mathrm{g}}{(\mathrm{m}_1 + \mathrm{m}_2)}\)

C. \(\mathrm{a} = \frac{\mathrm{m}_1}{(\mathrm{m}_1 + \mathrm{m}_2)\mathrm{g}}\)

D. \(\mathrm{a} = \frac{\mathrm{m}_2}{(\mathrm{m}_1 + \mathrm{m}_2)\mathrm{g}}\)
