Choose the correct options Consider following pair of forces of equal magnitude and opposite directions: (p) Gravitational forces exerted on each other by two point masses separted by a distance. (Q) Couple of forces used to rotate a water tap. ( R ) Gravitional force and normal force experienced by an object kept on a table. For which of these pair//pairs the two forces do NOT cancel each others's translational effect?
