The acceleration of10 kg block when F = 30 N ,

Answer»

`2 m// s^(2)`
` 3 m// s^(2)`
`1 m//s ^(2)`
none of these

SOLUTION :
Common ACCELERATION

`a_(C) = (F)/(M_(1) + M_(2)) = (30)/(15) = 2m//sec^(2)`
`f_(2) - f_(1) = 5 xx a`
as `"" f_(2) - f_(1) = 35 Ngt f_("required")`
[`f_("required")` to have common acceleration = 10 N]
