Problem

A square metal plate of side

20\,\text{cm}

is pressed against a vertical wall by a force of

500\,\text{N}

that makes an angle of

30^{\circ}

with the normal to the plate. What is the pressure exerted on the wall? a)

6.3 \times 10^{3}\,\text{Pa}

8.7 \times 10^{3}\,\text{Pa}

1.1 \times 10^{4}\,\text{Pa}

1.3 \times 10^{4}\,\text{Pa}
