Answer:
Given that
speed u=4*10^6 m/s
electric field E=4*10^3 N/c
distance b/w the plates d=2 cm
basing on the concept of the electrostatices
now we find the acceleration b/w the plates to find the horizontal distance traveled by the electron when it hits the plate.
acceleration a=qE/m==
m/s
now we find the horizontal distance traveled by electrons hit the plates
horizontal distance
=
== 3 cm

Answer:
Fundamental frequency is 200 Hz.
Explanation:
It is given that,
Frequency of the 3rd harmonic is 600 Hz.
Let f is the fundamental frequency. We need to find the value of f. The frequency of third harmonic is given by :
So, fundamental frequency f is equal to :
f = 200 Hz
So, the fundamental frequency of the harmonics is 200 Hz. Hence, this is the required solution.
Any point in the wire has 1.12 x . electrons flow per second.
- Electric current in a wire, where electrons serve as the charge carriers, is a measurement of the amount of charge that moves through any point of the wire in a given amount of time.
- A free electron is drawn to a proton to become neutral if an electron is added to the wire.
- Lack of electrons can result from pushing electrons out of their orbits.
- Electric current is the name given to the constantly moving electrons in wire.
The current is the quantity of charge Q flowing through a certain point of the wire in a time interval of .
I = .
by using this relationship
I=1.80 A, we can find the charge passing any point in the wire in 1 second:
Electric Charge, Q = 1.80 C.
To find how many electrons corresponds to this charge, we should divide this value by the charge of a single electron
charge of the electron = 1.6 x C.
No. of Electrons = Q/q = = 1.12 x

The relation between electric field intensity, electric force and charge is given as follow,
Where,
F = Force
q = Charge
The direction of force on a charge placed in an electric field is same as the direction of electric field if the charge has positive polarity and opposite if charge has negative polarity.
Replacing we have that
As direction of force is upward and polarity of charge is negative, hence the direction of field will be opposite to that of force. Therefore direction of field is downward.
