Answer:
Components: 0.0057, -0.0068. Magnitude: 0.0089 m/s
Explanation:
The displacement in the x-direction is:
While the displacement in the y-direction is:
The time taken is t = 304 s.
So the components of the average velocity are:
And the magnitude of the average velocity is
Answer:
The force will be 54.0 units
Explanation:
The magnitude of the electrostatic force between two charged objects is given by Coulomb's Law:
where
k is Coulomb's constant
q1, q2 are the magnitude of the two charges
r is the separation between the two charges
From the equation, we see that the magnitude of the force is directly proportional to the charge of object 2:
In this problem, the initial force between the two objects is
F = 18.0 N
And so, when the charge on object 2 is tripled,
The new electrostatic force will be
So, the force will also triple: since the original force was 18.0 units, the new force will be
