Asmall screwdriver is used to pry apart the two coils of
acircular key ring. the wedge angle of the screwdriver blade is
16degrees and the coefficient of static friction is 0.12 between
thecoils and the blade. knowing that a force p of magnitude 3.5 n
wasrequired to insert the screwdriver to the equilibrium
positionshown, determine the magnitude of the forces exerted on the
ring bythe screwdriver immediately after force p is removed.
