What fraction of 5 MeV α particles will be scattered through angles greater than 4.5° from a gold foil (Z = 79, density = 19.3 g/cm3) of thickness 10-8 m?

The fraction of particles is

Explanation:

Given :

Alpha particle atomic no.

Gold foil atomic number

Thickness m

Density

Kinetic energy of alpha particle V

V

Scattered angle 4.5°

Fraction of incident particle scattered at angle is,

Where number density of particle,

For calculating value of

Where ,           ( Mass number of gold foil )

Put the all value in above equation,

Therefore, the fraction of particles is

an electric circuit

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
