electron with speed 
and a photon with speed c have the same de-Broglie wavelength. If the kinetic energy and momentum of electron are 
and 
and that of photon are 
and 
respectively. Which of the following is correct?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As we know de-broglie wavelength, 
For photon,
Energy of photon, 
From this we get momentum of photon,
For electron, Energy, 
Momentum, 
Now according to question, 
Now, 
will be,
