Jerimiah Fitzgerald · Answer 1

The force acting on the block along the plane = mg Sin 45 = 0.707 x mg

The normal force acting on the block = mg Cos 45 = 0.707 x mg

Here, both the forces are equal in magnitude and the direction is different.

The net force is acting along the plane and the normal force is acting perpendicular to the plane.
