Problem

Two point masses

m

and

M

attract each other with a force

F

when their centres are separated by a distance

d

. If

m

is made three times larger,

M

is made two times larger and the separation is reduced to

\dfrac{d}{2}

, what will be the new force

F'

in terms of the original force

F

? a)

12F

24F

\dfrac{3}{2}F

6F
