A block is placed on an inclined plane as shown in figure. What must be the friction force between block and inclined if the block is not to slice along the inclined when the incline is accelerating to the right at `3 m//s^(2) ( sin 37^(@) = (3)/(5))`? `(Take g = 10 m//s^(2))`

Explanation

`N cos 37^(@) + f sin 37^(@) = mg` …(i)
`N sin 37^(@) - f cosi 37^(@) = ma` …(ii)
On solving these two equation , we get
`f = 3.6m`
`= (9)/(25) mg`
