Question

State the universal law of gravitation and derive their equation for the universal gravitational constant

Answer 1

universal law of gravitation says that every object in univers atract every other object in the universe
and newtons also tell that the force of atraction depents upon the mass of 2 body and distance between them
it means
gravitational force is equaly proportion to product of masses of two bodies
gravitational force inversally proportion to square of distance between to body
let the proportional sign be♤ then
force♤mass1×mass2
and
force♤1/distance square
so we can say that
force♤mass1×mass2/distance square

to replace proportion sign we must use any constant so
force=G×mass1×mass2/r^2(distance square)
value of G is 6.67×10^-11

Answer 2

❤️HEY ALLY❤️

☑️ANSWER

➡️The universel law of gravitation states that every object in universe attracts other with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between them

☑️ equation

➡️two objects of masses m1 and m2

➡️let the distance between them be r

➡️F is proportional to product of their masses

➡️therefore
✔️F ∝M×m ....1

✔️F∝1/d square...2

✔️ combining equation 1 and 2 we get

✔️F∝M×m/dd or

✔️F = G M×m/dd

✔️here G is constant
