A body of mass 2 kg is acted upon by two perpendicular forces 4 N along the X-axis and 3 N along the Y-axis. What is the magnitude of the acceleration of the body ?

Answer»

`1.5 ms^(-2)`
`2.0 ms^(-2)`
`2.5 ms^(-2)`
`3.5 ms^(-20)`

SOLUTION :Here, `F = SQRT(4^(2) +3^(2)) = 5N`
:.acceleration `a = F//m=(5)/(2)=2.5m//s^(2)`
Hence correct CHOICE is (C).
