Answer:
The magnitude of the electric field between the plates is half its initial value.
Explanation:
We know the electric field E = V/d where V = voltage applied and d = separation between plates.
Since V is constant and V = Ed,
So, E₁d₁ = E₂d₂ where E₁ = initial electric field at separation d₁, d₁ = initial separation of plates, E₂ = final electric field at separation d₂ and d₂ = final separation of plates.
So, E₂ = E₁d₁/d₂
Now, the distance between the plates is twice their original separation. Thus, d₂ = 2d₁
So, E₂ = E₁d₁/2d₁ = E₁/2
So, E₂ = E₁/2
Thus, the magnitude of the electric field between the plates is half its initial value.
Answer:
Yes it does.
Explanation:
"The North Magnetic Pole moves over time due to magnetic changes in Earth's core.

It does move around as the magnetic north does.
Answer:
New force, ![F'=48\times 10^3\ N](https://tex.z-dn.net/?f=F%27%3D48%5Ctimes%2010%5E3%5C%20N)
Explanation:
It is given that,
Force acting between two charged particles, ![F=7.5\times 10^2\ N](https://tex.z-dn.net/?f=F%3D7.5%5Ctimes%2010%5E2%5C%20N)
We need to find the force if they are moved so they are only one-eighth as far apart.
The force between two charged particles separated at a distance of r is given by :
............(1)
If the charges are one-eighth as far apart then, r' =(1/8)r and new force is given by :
..........(2)
Dividing equation (1) and (2) :
![\dfrac{F}{F'}=\dfrac{1}{64}](https://tex.z-dn.net/?f=%5Cdfrac%7BF%7D%7BF%27%7D%3D%5Cdfrac%7B1%7D%7B64%7D)
![F'=7.5\times 10^2\ N\times 64](https://tex.z-dn.net/?f=F%27%3D7.5%5Ctimes%2010%5E2%5C%20N%5Ctimes%2064)
F' = 48000 N
or
![F'=48\times 10^3\ N](https://tex.z-dn.net/?f=F%27%3D48%5Ctimes%2010%5E3%5C%20N)
Hence, this is the required solution.

If the distance around the equator is reduced by half, then the radius is also reduced by half.
Since the acceleration due to gravity is proportional to 1/(radius²),
the acceleration changes by a factor of 1/(1/2)² = 1/(1/4) = <em>4 </em>.
The acceleration due to gravity ... and also the weight of everything on Earth ...
becomes <em>4 times what it is now</em>.
