2qs about wave nature of particlr and electron
Frank hrtz tell about nature
Photoelectric curent depend on
Nucleus radius R=R0 A1/3
Quark radius of the order of nm
Wavelength associated with e having potential 50V
Which is true about two object thrown at different angle and different velocity
Self inductance
given L, ∆I, ∆t
A particle thrown downward. Force acting is bv.
Height as fn of time
Acha fission ka question tha k
Which statement is true?
Energy released in fission is larger than energy released in fusion
Energy released in fission per nucleon is larger than energy released in fusion
Energy released per nucleon in fission is less than energy released in fusion
All of them
......
Hydrogen atom at distance of 0.053Å have speed
C/2
C/10
C/137
.....

Optics k questions thy
Coordinates x, y into spherical
Formula thy
Distance of object given, distance at which observer stands is given, how much distance should observer move to focus the image.
Same question came 2 values change
Formula of escape velocity
Emf 3,4 question
Beta decay is due to
Hydrogen atom related 2
