Question

What is the static force between two charged particles if the charge on object 1 is + 8.6 coulombs and the charge on object 2 is -7.4 coulombs. The distance between the objects is 5.5 meters

Answer 1

Given:

The charge on the object 1, q₁=8.6 C

The charge on object 2, q₂=-7.4 C

The distance between the objects, d=5.5 m

To find:

The force between the charges.

Step-by-step explanation:

From Coulomb's law, the magnitude of the force between two charges is given by,

`F=(k|q_1||q_2|)/(d^2)`

On substituting the known values,

`\begin{gathered} F=(9*10^9*8.6*7.4)/(5.5^2) \\ =19*10^9\text{ N} \\ =19\text{ GN} \end{gathered}`

Final answer:

The force between the charges is 19 GN
