    Two bodies having masses \[{{m}_{1}}\] = 40g and \[{{m}_{2}}\] =            60g are attached to the ends of a string of negligible mass and suspended from massless       pulley. The acceleration of the bodies is:

    A) 1 nVs2                  

    B) 2m/s2

    C) 0.4 m/s2              

    D) 4 m/s2

    Correct Answer: B

    Solution :

    Acceleration\[a=\frac{{{m}_{2}}-{{m}_{1}}}{{{m}_{1}}+{{m}_{2}}}g\] \[=\frac{60-40}{60+40}\times 10\] \[=\frac{20\times 10}{100}\] \[=2m/{{s}^{2}}\]
