Question

Proof:
f = R/2 ( from ch. light)​

Answer 1

Explanation:

Gravity can never be ZERO. Zero gravity is a myth and doesn't exist. You cant find a term like “ZERO GRAVITY” in any of technical documentation because they use another term for the feeling of weightlessness and its called “MICROGRAVITY”. Microgravity means very less gravity not zero gravity.

The mathematical expression for gravity is F = G (M1 x M2)/ R^2

G - universal gravity constant.

M1 - Mass of 1st Body.

M2 - Mass of 2nd Body.

R - Distance between object’s center of gravity.

Now as per above equation the following inferences can be drawn -

1 - Gravity force can be zero if either of the masses is zero (practically not feasible).

2 - Gravity can tend towards zero (not equal to zero) when distance between the objects is infinity.

Therefore we can conclude that at any given point the gravity cannot be zero, It can tend towards zero which is termed as MICROGRAVITY.

Hope this helps.
