(i) (A) Gravitational force always exists between any two bodies in the universe.

(ii) (A) The orbital velocity of a satellite in an orbit of radius r is given as

(iii) (C) According to universal law of gravitation

(iv) (C) The orbital velocity of a satellite in an orbit of radius r is given as

Therefore, it depends on the mass of the planet

(v) (A) The orbital velocity of a satellite in an orbit of radius r is given as

Therefore

Therefore, speed increases as the orbit is lowered
