You and a friend are spending the weekend making up missed lab experiments. you are on to second - semester material and are studying the electrostatic interaction of two charges. you notice that two charges are exerting a certain force on one another. if the distance between two electric charges doubles, then the force they exert on each other changes by how much?
2 times as large
4 times as large
1/4 as large
1/2 as large

1/4 as large  

Explanation:

Lets take

q₁ and q₂ are the charge on the particle and d is the distance between them.

We know that electrostatics between two particle given as

When distance become double d'= 2 d

So new force F'

It means that force will become one forth of initial force.

So answer is 1/4 as large .

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
