प्रश्न
An apple of mass 100 g falls from a tree because of gravitational attraction between the earth and the apple. If the magnitude of force exerted by the earth on the apple be F1 and the magnitude for force exerted by the apple on the earth be F2, then :
विकल्प
F1 is very much greater than F2
F2 is very much greater than F1
F1 is only a little grater than F2
F1 and F2 are exactly equal
उत्तर
F1 and F2 are exactly equal in magnitude
