The situations are shown in fig(a) & (b), in each case, `m_1`=3kg and `m_2 =4`kg. If `a_1 , a_2` are the respective accelerations of the blocks in these situations, then the values of `a_1` and `a_2` are respectively [g=10 `ms^(-2)`]

Options

A. `(10)/(7) ms^(-2) , (25)/(7) ms^(-2)`
B. `(30)/(7) ms^(-2) , (5)/(7) ms^(-2)`
C. `(40)/(7) ms^(-2) , (10)/(7) ms^(-2)`
D. `(20)/(7) ms^(-2) , (10)/(7) ms^(-2)`

Answer

C
