1 Fig. 5 shows a block of mass 10 kg at rest on a rough horizontal floor. A light string, at an angle of \(30 ^ { \circ }\) to the vertical, is attached to the block. The tension in the string is 50 N .
The block is in equilibrium.

- Show all the forces acting on the block.
- Show that the frictional force acting on the block is 25 N .
- Calculate the normal reaction of the floor on the block.
- Calculate the magnitude of the total force the floor is exerting on the block.
