Charge q is 1 unit of distance away from the source charge S. Charge p is two times further away. The force exerted between S and q ls the force exerted between S and p.

The correct answer will be "1/16".

Explanation:

The force or distance between two substances in charge seems to be inversely proportional to the square of the size of the particles.  

The exerted force between "S" and "q" will be:

⇒   ...(equation 1)

The exerted force between "S" and "p" will be:

⇒   ...(equation 2)

Now,

On the comparison of "equation 1" and "equation 2", we get

⇒  

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered
