Question

calculate the value of g from Newton's universal law of gravitation​

Answer 1

Answer:

g=9.86 m/s^2

Explanation:

let an object of mass m is falling on the surface of the earth within an acceleration due to gravity, g. Then-

F=mg

let Me be mass of earth and distance between the object and earth is Re. Then by universal law of gravitaion----

F= G Me m

-----------

Re^2

(since f= mg)

mg = G Me m

---------

Re^2

g= G M

----

Re^2

g= (6.67×10^-11) × (6 × 10^24)

------------------

(6.4×10^6)^2

g= 9.86 m/s^2
