Alfalfa pellets are placed on a horizontal plywood surface and the plywood is gradually tilted until the pellets begin to slide across the surface Sketches of the forces acting on a single pellet are shown below 0 00 R F n F a If Fg is the gravitational force acting on the pellet develop expressions for the magnitudes of F and F as a function of Fg and the angle 0 at which the plywood is inclined If the weight of a pellet is 0 35 g 0 00343 Newtons evaluate the magnitudes of F and F when 0 10 b Estimate the angle 0 at which the pellets will begin to slide
