Answer:
the bunch of 23 electrons must be placed on y axis at coordinate y = - 24.35 m.
Explanation:
As we know that the gravitational force on electron at y = 0 is counter-balanced by the weight of the electron
So we have
here we have
also we know that
so we will have
so the bunch of 23 electrons must be placed on y axis at coordinate y = - 24.35 m.
Answer:
Explanation:
= v/f
^That is the formula we are going to use.
Now, we were given the speed (v), which is 20.
Now we need to find frequency, in order to solve for the wavelength.
Frequency is the amount of waves in a fixed unit of one second, meaning our F value is the value of 5 divided by 4.
5/4 = 1.25
Therefore our F is 1.25
Now lets plug it in
= v/f
= 20/1.25
= 16
Conversion:
= 8
(a)
The relationship beween centripetal acceleration and angular speed is
where
is the angular speed
r is the radius of the circular path
Here we gave
is the centripetal acceleration
r = 5.15 m is the radius
Solving for , we find:
(b) 21.3 m/s
The relationship between the linear speed and the angular speed is
where
v is the linear speed
is the angular speed
r is the radius of the circular path
In this problem we have
r = 5.15 m
Solving the equation for v, we find
