Two electrically opposite charges are separated by a fixed distance. Which action will provide the greatest increase in the force of attraction between the charges?

Explanation:

The electric force between charges is given by the formula as follows :

k is electrostatic constant

r is distance between charges

Here, charges are equal and opposite. So,

It is clear the force is inversely proportional to the distance between charges and directly proportional to the product of charges. So, greatest force will be providing by :

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

where are the vectors ?
