A block of mass m slides along a floor while a force of magnitude F is applied to it at an angle `theta` as shown in figure. The coefficient of kinetic friction is `mur`. Then, the block's acceleration 'a' is given by:
(g is acceleration due to gravity)

A

`F/m cos theta - mu K (g - (F)/(m ) sin theta )`

B

`F/m cos theta + mu K (g - (F)/(m ) sin theta )`

C

`- F/m cos theta - mu K (g - (F)/(m ) sin theta )`

D

`F/m cos theta - mu K ( g + (F)/(m) sin theta)`
