Problem

A compressor pushes on a flat plate of area

0.05\,\text{m}^2

to obtain a pressure of

4\times10^{5}\,\text{Pa}

inside a test chamber. If only

80\%

of the compressor’s force actually reaches the plate, what force must the compressor generate? a)

2.0\times10^{4}\,\text{N}

3.2\times10^{4}\,\text{N}

2.5\times10^{4}\,\text{N}

1.6\times10^{4}\,\text{N}
