What happens to a charged particle placed in an electric field?
It will accelerate in the direction determined by its charge and the electric field.
What is the formula for calculating work done on a charge in an electric field?
W = QV, where W is work in joules, Q is charge in coulombs, and V is voltage in volts.
How is one volt defined?
One volt is the potential difference when one joule of work is done in moving one coulomb of charge.
What form of energy can a charge gain when placed in an electric field?
The energy can be in the form of kinetic energy.
What is the relationship between work done on a charge and its gain in kinetic energy?
The work done on a charge is equal to its gain in kinetic energy.
What is Fleming’s right-hand rule used for?
It is used to determine the direction of force on a charge moving in a magnetic field.
What does the first finger represent in Fleming’s right-hand rule?
The direction of the magnetic field (from north to south).
What does the second finger represent in Fleming’s right-hand rule?
The direction of current (electron flow).
What does the thumb represent in Fleming’s right-hand rule?
The direction of motion of the charge.
What are particle accelerators used for?
They are used to accelerate elementary particles to high energies for research and medical purposes.
What is a linear accelerator?
A type of particle accelerator that accelerates particles in a straight line.
What is the purpose of a vacuum chamber in a particle accelerator?
To prevent air or dust particles from obstructing the path of accelerated particles.
What is alpha decay?
A process where an alpha particle (2 protons and 2 neutrons) is ejected from an atom’s nucleus.
What happens to the atomic number during alpha decay?
The atomic number decreases by 2.
What is beta decay?
A process where a neutron breaks down into a proton and an electron, ejecting the electron from the nucleus.
What happens to the atomic number during beta decay?
The atomic number increases by 1.
What is the representation of an alpha particle in nuclear equations?
4 2He.
What is the representation of a beta particle in nuclear equations?
0 1e⁻.
How do you calculate the increase in speed of an alpha particle in an electric field?
Using the formula W = QV, where W is the work done on the charge.
What is the significance of the total atomic number and mass number in nuclear equations?
They must be the same on both sides of the equation to conserve mass and charge.
What is an isotope?
Atoms of the same element that have different numbers of neutrons.
What is the mass number of an atom?
The total number of protons and neutrons in the nucleus.
What is the atomic number of an element?
The number of protons in the nucleus of an atom.
What is the role of electromagnets in particle accelerators?
To confine the beam of particles within the accelerator.
