A symmetrical uniform solid cube of the 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 the coefficient of friction $μ$ is the same for both wall and floor, the minimum value of $μ$ so that cube does not slip is

Question

Options:

Answer:

B

Solution:

At an angle $45 °$ , $N$ and $M g$ balance each other. As they both pass through the centre of mass, so no need for friction to balance it
