If the universe is expanding, are there more structures such as galaxies, stars, etc., towards its center rather than at the newer edge? Is the rate of acceleration of expansion of the universe known? Will the universe keep on expanding forever or is there enough gravity to slow down the expansion?
Since 4 is in the denominator of the expression for force, we see that with the raising of satellite to newer orbit the gravity becomes 1/4 (or 1/16 of the value at the surface of earth). (b).
