Answer:
Final speed of the box after it has moved to x = 10 is given as
v = 3.35 m/s
Explanation:
As we know by work energy theorem that work done by all the forces is equal to the change in its kinetic energy
Here work done by external force + work done by friction = change in kinetic energy of the box
so we have

![F x - \mu mg x = \frac{1]{2}mv^2](https://tex.z-dn.net/?f=F%20x%20-%20%5Cmu%20mg%20x%20%3D%20%5Cfrac%7B1%5D%7B2%7Dmv%5E2)

Answer: The electrostatic force will be the same
Explanation:
According to Coulomb's Law, when two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies or particles.
In this sense, this law states the following:
"The electrostatic force
between two point charges
and
is proportional to the product of the charges and inversely proportional to the square of the distance
that separates them, and has the direction of the line that joins them"
(1)
Being
is a proportionality constant.
Now, if each
and
are increased by 6, and the distance between them as well, we will have the following:
(2)
(3)
Simplifying:
(4)
Comparing (1) with (4) we can see the electrostatic force is the same.
1km=1000m; 1hr=3600secs
1km/hr=1000/3600= 5/18m/sec
To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.
18kmh-1= 18•5=90
90/18=5
