Answer» <p>3)On Earth, Gravity is minimum on equator and maximum on poles.</p><p>Equator-it is the largest circle on earth which divides earth in two equal halves (southern hemisphere and northern hemisphere) . It makes zero degree angle with centre of earth. In other words, earth is divided in latitudes ranging from 0 degree to 90 degree (north or south depending on which hemisphere you move) subject to the angle they make with centre of earth.</p><p>P. S. Fun fact gravity is maximum on surface of earth, ot decreases if you move away from earth or go inside earth, because gravity depends on mass of the object.</p><p>P. P. S every object in the universes exerts gravitational attraction force on every other object</p>
