Calculate the force with which you attract the earth.
Answer
View full question & answer→Consider that a man is standing on the surface of the Earth. Force acting on the man $= mg$
Here, $m =$ mass of the man and $g =$ acceleration due to gravity on the surface of earth $(= 10m/s^2)$ Assume that the mass of the man is equal to $65\ kg.$
Then $F = W = mg = 65 \times 10 = 650N =$ force acting on the man
$\therefore$ By Newton's third law $($action$-$reaction are always equal$),$ the man is also attracting the earth with a force of $650N$ in the opposite direction.
