Answer:
In order to make this force twice as strong, F' = 2 F, the distance would have to be changed to half i.e. r' = r/2.
Explanation :
The electric force between two point charges is directly proportional to the product of charges and inversely proportional to the square of the distance between charges. It is given by :
![F=\dfrac{kq_1q_2}{r^2}](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7Bkq_1q_2%7D%7Br%5E2%7D)
r is the separation between charges
![F\propto \dfrac{1}{r^2}](https://tex.z-dn.net/?f=F%5Cpropto%20%5Cdfrac%7B1%7D%7Br%5E2%7D)
![r=\sqrt{\dfrac{1}{F}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%5Cdfrac%7B1%7D%7BF%7D%7D)
If F'= 2F
![r'=\dfrac{1}{\sqrt{2F} }](https://tex.z-dn.net/?f=r%27%3D%5Cdfrac%7B1%7D%7B%5Csqrt%7B2F%7D%20%7D)
In order to make this force twice as strong, F' = 2 F, the distance would have to be changed to half i.e.
. Hence, this is the required solution.
Mass of 25 kg weight is 25/9.81 slug of mass.
Atomic disguise makes helium look like hydrogen. ... A helium atom consists of a nucleus containing two positively charged protons and two neutrons, encircled by two orbiting electrons which carry a negative charge. A hydrogen atom has just one proton and one electron
<span>Kinetic energy is a body that possesses by
virtue of being in motion. While potential energy possesses a body by virtue of
its position relative to others, stresses within itself, electric charge, and
other factors. As the “car” moves along the track its kinetic energy coverts to
potential energy when it moves up or down one of the hills. With the initial motion
already pushing it when it reaches a slope or dip it uses its own motion to
move along the track. </span>
<span>For
my track I used cardboard and for my “car” I used a spool of thread. The weight
of the cardboard is about .13 kg and the spool is about 0.9</span>
<span>P.s. these were my answers and I got a pretty good grade, for the weight of the track and "car" I did estimate it.</span>
Answer:
C. 0 N
Explanation:
In the absence of external forces, a body in motion will stay in motion.
F = ma
F = 6.0(0) = 0
