AIEEE, IIT-JEE Structure of Atom - Test 2

In the discharge tube emission of cathode rays requires
Low potential and low pressure
Low potential and high pressure
High potential and high pressure
High potential and low pressure
The minimum real charge on any particle which can exist is
Zero
Which of the following statement is incorrect
The charge on an electron and on a proton are equal and opposite
Neutrons has no charge
Electrons and protons have the same weight
The mass of a proton and a neutron are nearly identical
Ratio of masses of proton and electron is
Infinite
1.8
None of these
The mass of a mole of proton and electron is
2 gm
A mass spectrograph is an instrument which is capable of differentiating and identifying particles
Of different masses
Bearing different magnitude of charge
Bearing positive and negative charges respectively
Of different values of charge and mass ratio
Anode rays were discovered by
Goldstein
J. Stoney
Rutherford
J.J. Thomson
The nature of anode rays depends on
Nature of electrode
Nature of discharging tube
Nature of residual gas
All of these
Proton is
An ionized hydrogen molecule
An (-ray particle
A fundamental particle
Nucleus of heavy hydrogen
Penetration power of proton is
More than electron
Less than electron
More than neutron
None of these
The ratio of specific charge of a proton and an (-particle is
2 : 1
1 : 2
1 : 4
1 : 1
The e/m for positive rays in comparison to cathode rays is
Very low
High
Same
None of these
What is false to say about anode rays
Their e/m ratio depends upon the nature of residual gas
They are deflected by electrical and magnetic field
Their e/m ratio is constant
These are produced by ionization of molecules of the residual gas
Nuclei tend to have more neutrons than protons at high mass numbers because
Neutrons are neutral particles
Neutrons have more mass than protons
More neutrons minimize the coulomb repulsion
Neutrons decrease the binding energy
The proton and neutron are collectively called as
Deutron
Positron
Meson
Nucleon
