Answer 2

To Find :

Thrust and pressure on table top.

Formula:

${\pink{\tt{Thrust = force}}}$

${\pink{\tt{Thrust = mg }}}$

$pressure = \frac{thrust}{area}$

According to question

Thrust = mg

Thrust = 7.5 × 10

Thrust = 75 newton.

calculating pressure

$pressure = \frac{thust \: }{area}$

$pressure = \frac{75}{0.00096}$

$pressure = 7812.5 \: pascal$

Thrust on table Top = 75 newton.

Pressure on Table top = 7812.5 pascal.
