The Standard Model 2

Question 1

What are electric fields

Answer 1

An electric field is an area where a charged particle experiences force and the lines show how a positively charged particle would move in the field and the closer the lines are together the stronger the fields

Question 2

What is a uniform electric field

Answer 2

A uniform electric field has the same field strength everywhere in the field and the lines are equally spaced in a uniform field

Question 3

When is work done in a uniform electric field

Answer 3

Work is done when moving a charged particle in a uniform field and a charged particle can gain electrical potential energy by moving it through the field

Question 4

What is a volt defined as

Answer 4

On joule per coloumb

Question 5

Alpha particle

Answer 5

Helium nucleus (2 protons , 2 neutrons) : +2 charge

Question 6

Beta particle

Answer 6

Fast moving electron : -1 charge

Question 7

Neutron particle

Answer 7

0 charge

Question 8

Explain Magnetic fields in magnets

Answer 8

Magnets have a north and South Pole and produce a magnetic field and the lines always point from north to south

Question 9

What re the 3 types of particle accelerators

Answer 9

• linear
• circular
• synchrotrons

Question 10

Explain how linear accelerators work

Answer 10

• the particles pass through one tube the accelerate to the next tube. The particles spend the same time in each tube and therefore the tubes get longer since the articles that move through the get faster

Question 11

Explain how cyclotron accelerators work

Answer 11

• the high frequency a.c. Supply is used to change the direction of the electron field acting since the particles change direction crossing the gap
