Answered by harinderkhurpa

Consider a block of mass "m" placed on an inclined plane, which makes an angle q with the horizontal plane. The weight "W" of the block is acting vertically downward. The weight of the block can be resolved into two rectangular components:

wcosq and wsinq

other forces acting on the block are:

(i) Surface reaction (R) which is perpendicular to the plane

(ii) Force of friction (f) acting opposite to the direction of motion of block.

Let us take x-axis perpendicular to the inclined plane. If the block is at rest, then wsinq acting down the plane balances the opposing frictional force.

Applying 1st condition of equilibrium.
