THRUST

THRUST IS A FORCE OR A PULL BY THE BODY ON THE OTHER BODY. IT IS ALWAYS PERPENDICULAR TO THE AREA OF THE BODY EXERTED THE THRUST.

PRESSURE

THE THRUST APPLIED BY THE BODY PER UNIT AREA OF OTHER OBJECT IS KNOWN AS PRESSURE.

$mass = 7.5kg \\ thrust = mass \times gravity \\ \\ thrust = 7.5 \times 10 \\ \\ thrust \: = 75 \: newton.... |answer| \\ \\ dimension \: of \: the \: body \: (in \: meters) \\ \\ we \: need \: breadth \: and \: length \: only \\ \\ = 0.12 \times 0.08 \\ \\ area = 0.12 \times 0.08 = 96 \times {10}^{ - 4} {m}^{2} \\ \\ pressure = \frac{thrust}{area} \\ \\ pressure = \frac{75}{96 \times {10}^{ - 4} } \\ \\ pressure = \frac{75 \times {10}^{4} }{96} \\ \\ pressure = \frac{750000}{96} = 7812.5 \: pascal$
