# Find the pressure exerted by a book having mass 200gm and length of book is50cm and width is 30cm kept on a table.

$Pressure=\frac{Force}{Area}\phantom{\rule{0ex}{0ex}}Force=Mass\times acceleration.\phantom{\rule{0ex}{0ex}}Consideringaccelerationg=10m/s\xb2,\phantom{\rule{0ex}{0ex}}Mass=200g=0.2Kg\phantom{\rule{0ex}{0ex}}Length=50cm=0.5m\phantom{\rule{0ex}{0ex}}Breadth=30cm=0.3m\phantom{\rule{0ex}{0ex}}Hence,Area=0.15m\xb2\phantom{\rule{0ex}{0ex}}Force=0.2\times 10=2N\phantom{\rule{0ex}{0ex}}Therefore,Pressure=\frac{2}{0.15}\phantom{\rule{0ex}{0ex}}P=13.4N/m\xb2$
