A body of weight 12kg.wt is placed on a smooth plane inclined to the horizontal at an angle of measure 30° it is kept in equilibrium by horizontal force find the magnitude of each of the force and the reaction of the plane
magnitude of two forces
f1=12sin30
its direction in the direction of line of greatest slope
f2=12cos30
its direction in same direction of perpendicular line
اخر جزء لسه موصلتش له في المنهج بتاع reactionعرض
