Answer:
Explanation:
As we know that work done by electric force is given as
so here we know that charge is moving from
to another position
so we will have
Answer:
24 N
Explanation:
= mass of the cube =
Consider the three cubes together as one.
= mass of the three cubes together =
= acceleration of the combination = 2 ms⁻²
= Force applied on the combination
Using Newton's second law
= Force by the left cube on the middle cube
Consider the forces acting on left cube, from the force diagram, we have
As the distance between two charged objects increases, the strength of the electrical force between the objects <em>decreases</em>.
The correct answer is<span> number of oscillations in a given period of time
This is measured in what is called the Hertz measurement and the period of time is usually taken to be per second.</span>
The net force is 12 N to the left.
