Question

the electric force between two charged objects is 0.24 newtons. If the distance between them is increased by a factor of 4, what will be the new force?
Select one of the options below as your answer:

A.
0.03 newtons
B.
0.06 newtons
C.
0.12 newtons
D.
0.36 newtons
E.
0.96 newtons

Answer 1

the force is inversely proportional to distance squared

Answer 2

okay...
\[F=k/r ^{2}\]
here F=force ,k= some constant and r=distance

Answer 3

0.24=k/4^2

Answer 4

is that right?

Answer 5

nvm cant be

Answer 6

?

Answer 7

no...you have two situation...
\[F=k/r^2\]
here F=0.24 N
so k/r^2=0.24
now F'=k/(4r)^2
or F'=k/r^2*1/16
or F'=0.24/16

Answer 8

o.o15?

Answer 9

can u tell me the answer im seriously feeling super dumb right now

Answer 10

thanks for the help
