Question

the force keeping the moon in its orbit round the earth is inversely proportional to the square of the distance from the earth.if F =6×10^5KN and R =8×10^8.find the equation connecting Fand R.​

Answer 1

9514 1404 393

Answer:

F = 3.84×10^23/R²

Explanation:

No units are given for distance, so we cannot give a constant of proportionality that has suitable units.

The general form for inverse square variation is ...

F = k/R²

Then the value of k can be found from ...

k = F·R² = (6×10^5)(8×10^8)^2 = 3.84×10^23

The formula relating the given F and R is ...

F = 3.84×10^23/R²
