QAIPMT-2011-Ph-1930: NEET 2011 Physics - Class 11 AIPMT-2011-Ph-1930 Solution: In the Davisson and Germer experiment the velocity of electrons …
In the Davisson and Germer experiment the velocity of electrons emitted from the electron gun can be increased by increasing the potential difference between the anode and filament increasing the filament current decreasing the filament current decreasing the potential difference between the anode and filament
Multiple Choice Options
- A 40 m
- B 50 m
- C 60 m
- D 20 m
Step-by-Step Verified Solution
For maximum range, the angle of projection,
_ = 45�.
_ R = u 2 sin _ 2 _ g
= ( 20 ) 2 sin _ ( 2 _ 45 _ ) 10
= 400 _ 1 10 = 40 m
