Answer:
at the beginning:
when the plates are pulled apart:
Explanation:
The capacitance of a parallel-plate capacitor is given by
where
k is the relative permittivity of the medium (for air, k=1, so we can omit it)
is the permittivity of free space
A is the area of the plates of the capacitor
d is the separation between the plates
In this problem, we have:
is the area of the plates
is the separation between the plates at the beginning
Substituting into the formula, we find
Later, the plates are pulled apart to , so the capacitance becomes

B) the distance between the charged particles is decreased.
C) the magnitude of the charge on both the particles is decreased.
D) the magnitude of the charge on one of the particles is decreased.
The force of repulsion between two like-charged particles will increase if the distance between the charged particles is decreased.
According to Coulomb's law: The magnitude of each of the electric forces with which two point-at-rest charges interact is directly proportional to the product of the magnitude of both charges
And inversely proportional to the square of the distance that separates them and has the direction of the line that joins them.
The formula will be given as:
We can see that the force is inversely proportional to the distance of the two charges.
To know more about coulomb's law follow
Answer:
B). the distance between the charged particles is decreased.
Explanation:
2)Find the tension in the string. (N)
3)Find the speed of each object 2.50 s after being released from rest. (m/s)
Answer:
Part a)
Part b)
Part c)
Explanation:
For m2 mass along the inclined plane we can write
for m1 mass we can write equation in vertical direction
so we will have
so we have
now plug in all data in it
Part b)
from above equation
Part c)
Speed of the object after t = 2.50 s
