The electric force is 
(attractive)
Explanation:
The magnitude of the electric force between two charges is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, we have the following:
(charge 1)
(charge 2)
r = 0.025 m (distance)
Substituting, we find the electric force between the two charges:
And the negative sign means the force is attractive, since the two charges have opposite sign.

<span>Inertia is a property of matter
i hope this help</span>
Answer:
<h2>17.1 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3800 g = 3.8 kg
We have
force = 3.8 × 4.5
We have the final answer as
<h3>17.1 N</h3>
Hope this helps you
<span>The energy source used to produce most of the electrical energy in the United States is Fossil fuels. Fossil fuels are generated over a long period of time by decomposition of dead flora and Fauna. Fossil fuels consists of three things- Coal, Petroleum and Natural Gas. Natural gas approx contributes 34%, Coal approx contributes 30% and Petroleum approx contributes 1% of total energy produced in US.</span>
