Representation of data — practice question
A uniform solid cone has weight $5\,\text{N}$ and a base radius of $0.1\,\text{m}$. $AB$ is a diameter of the cone’s base. The cone is maintained in equilibrium, with $A$ touching a rough horizontal surface and $AB$ vertical, by a force applied at $B$. This force has magnitude $3\,\text{N}$ and is parallel to the axis of the cone (see diagram).
