A symmetrical uniform solid cube of side 5 m is placed on a horizontal surface beside a vertical wall, one side of the cube is making an angle 45 ° with the floor as shown. If coefficient of friction μ is the same for both wall and floor, the minimum value of μ so that cube does not slip

Question

A symmetrical uniform solid cube of side 5 m is placed on a horizontal surface beside a vertical wall, one side of the cube is making an angle 45 ° with the floor as shown. If coefficient of friction μ is the same for both wall and floor, the minimum value of μ so that cube does not slip, μ = 1, μ = 0, μ = 1 3, Impossible to balance for any value of μ

At angle 45 ° , N and Mg balance each other, they both pass through centre of mass, so no need for friction to balance it
