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 65kg.
Then $F = W = mg = 65 × 10 = 650N =$ 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.
