Two bodies of mass 6 kg and 4 kg are tied to a string as shown in the following figure. If the table is smooth and pulley frictionless, then acceleration of mass 6 kg will be (`g =10 ms^(-2)`)

Options

A. `60 ms^(-2)`
B. `40 ms^(-2)`
C. `6 ms^(-2)`
D. `4 ms^(-2)`

Answer

C

Explanation

Adding (1) and (2)
`6a=10a rArr a=(6g)/(10)=6ms^(-2)`
