The flux of `alpha-`particle at `2^@` is `1 xx 10^6`. The flux of `alpha-`particle at angle `60^@` is

In Rutherford scattering experiment, the number of alpha -particles scattered at 60^(@) is 5 xx 10^(6) . The number of alpha -particles scattered at 120^(@) will be

Alpha (alpha) particles are

alpha -particles and beta -particles

The number of alpha particles scattered at 60^(@) is 100 per minute in an alpha particle scattering experiment. Calculate the number of alpha particles scattered per minute at 90^(@) .

Charge of an alpha- particle is +3.2xx10^(-19)C . What force will act on the alpha - particle in an electric field of intensity "4000 N.C"^(-1) ?

In the Rutherford scattering experiment the number of alpha particles scattered at an angle theta=60^@ is 12 per min.The number of alpha particles per min when scattered at angle of 90^@

In an alpha -particle scattering experiment, the number of particles scattered at an angle of 90^@ is 100 per minute. Calculate the number of particles scattered at an angle of 60^@

An alpha particle is accelerated in a cyclotron with dees of radius 40 em and operating at frequency of 20 MHz. Calculate the kinetic energy of the alpha particle if magnetic field in cyclotron ia 1 tesla. Given, mass of alpha particle m_(alpha) = 6.65 xx 10^(-27) kg and charge of alpha - particle q_(alpha) = 3.2 xx 10^(-19) C .
