if the cathode and the anode are kept at the same potential, the emitted electrons have

A

the same KE equal to 1.36 eV

B

the average KE equal to `((1.36)/(2))` eV

C

the maximum KE equal to 1.36 eV

D

the minimum KE equal to 1.36 eV

Text Solution

Verified by Experts

The correct Answer is:
C

`V_S=1.36V`
`eV_S=1.36eV`
or `(1)/(2)m(v_(max))^(2)=1.36eV`
i.e., various electrons hace KE between zero and 1.36 eV.

The cathode and anode in a photocell are respectively.

In a photoelectric experiment a parallel beam of monochromatic light with power of 200 is incident on a perfectly absorbing cathode of work function 6.25. The frequency of light is just above the threshold frequency so that the photoelectrons are emitted with negligible kinetic energy. Assume that the photoelectron emission efficiency is 100%. A potential difference of 500 is applied between the cathode and the anode. All the emitted electrons are incident normally on the anode and are absorbed. The anode experiences a force 10 due to the impact of the electrons. The value of is __________. Mass of the electron 910 and 1.01.610.

In an X - ray tube , electrons emitted from a filament (cathode) carrying current hit a target (anode) at a distance d form the cathode. The target is kept at a potential V higher than the cathode resulting in emission of continuous of and charateristic X - rays. It the filament current I is decreased to (I)/(2) , the potential difference V is increaed to 2v, and the separation distance d is reduuced to (d)/(2) ,then

The graph between photo electric current and cathode potential when the anode is kept at zero potential, for light of two different intensities out of the same frequency looks like the one:

The cathode its 8 xx 10^(14) electrons per second, when heated. When 400 V is applied to anode all the emitted electrons reach the anode. The charge on electron is 1.6 xx 10^(-19)C . The maximum anode current is

(a) Estimate the speed with which electrons emitted from a heated cathode of an evacuated tube impinge on the anode maintained at a potential difference of 500 V with respect to the cathode. Ignore the small initial speeds of the electrons. The specific charge to of the electron, i.e., its e//m is given to 1.76xx10^(11)Ckg^(-1) . (b) Use the same formula you employ in (a) to obtain electron speed for an anode potential of 10 MV. Do you see what is wrong? In what way is the formula to be modified?

Cathode rays have same charge to mass ratio as
