Question

If the distance between two objects decreases to 25%, then what % does the force of gravitation change. NO SPAM AND GET MARKED AS BRAINLIEST

Answer 1

Answer:

77%

Explanation:

Fo=Gm1×m2/(r)²..........................................eq(1)

and decreased by 25% or  0.25 times

so remainig distance is 0.75 ties of orignal distance

on putting

Fnew=Gm1m2/(0.75r)²  ..............eq(2)

divideng eq(1)and eq(2)

get Fo/Fnew=(0.75r)²/(r)²

Fnew=Fo/0.75²

which equal to

Fnew=1.77Fo

then for percentage increase

Fnew-Fo=(1.77-1)=0.77

on percentage

it may 77%
