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/s2) 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.
