Question

If the mass of one of two particles is doubled and the distance between them is doubled, the force of attraction between the two particles will

a
decrease

b
increase

c
remain the same

Answer 1

a) decrease

Step-by-step explanation:

Force of attraction is directly dependent on masses (or charges) and inversely on (the distance between squared )

F = m1m2/ r^2 now--- double one mass and double the r

F = 2 m1m2/ (2r)^2 = 2/4 m1m2/r^2 = 1/2 m1m2 /r^2 <===1/2 the original
