Question

il Derive how does the value of gravitat
ale value of gravitational force F between two obiects change when
a distance between them is reduced to half and
b. mass of an object is increased four times.​

Answer 1

Step-by-step explanation:

force=gravitational constant×product of masses/d²

d= distance

let distance be x

force=G×nass1×masss2/x²

if distance is halved then it would be x/2

force=G×mass1×mass2/(x/2)²

G×mass1×mass2÷x²/4 do the division

g×mass1×mass2×4/x²

force will become 4 times

let mass of the first object be y

force =G× y×mass2/distance²

four times the mass of 1st object =4y

force=G×4×y×mass2/distance²

by the equations the force will be 4 times

for answer, divide second equation by the first one
