In a Geiger Marsden experiment, calculate the distance of closest approach to the nucleus of Z=80, when an `alpha`-particle of `8 MeV` energy impings om it before it comes momentarily to rest and reverses its direction.

In a Geiger- Marsden experiment, calculate the distance of closest approach to the nucleus of Z=80, when an alpha particle of 8 Me V energy impinges on it before it comes momentarily to rest and reverses its direction. How will the distance of closest approach be affected when the kinetic energy of the alpha- particle is doubled ?

In a Geiger- Marsden experiment, calculate the distance of closest approach to the nucleus of Z=80, when an alpha particle of 8 Me V energy impinges on it before it comes momentarily to rest and reverses its direction. How will the distance of closest approach be affected when the kinetic energy of the alpha- particle is doubled ?

In a Geiger-Marsden experiment, calculate the distance of the closest approach to the nucleus of Z = 80, when an a-particle of 8 MeV energy impinges on it before it comes momentarily to rest and reverses its direction. How will the distance of the closest opproach be affected when the kinetic energy of the o-particle is doubled?

In a Geiger - Marsden experiment, calculate the distance of closest approach to the nucleus of Z=75, when an alpha - particle of 5 Me V enery impinges on it before it comes momentarily to rest and reverses its direction. How will the distance of closest approach be affected when the kinetic energy of the alpha -particle is doubled ?

In a Geiger - Marsden experiment, calculate the distance of closest approach to the nucleus of Z=75, when an alpha - particle of 5 Me V enery impinges on it before it comes momentarily to rest and reverses its direction. How will the distance of closest approach be affected when the kinetic energy of the alpha -particle is doubled ?

In the original experiment, Geiger and Marsden calculated the distance of closest approach to the gold nucleus (Z=79)- of a 7.7MeV alpha particle before it comes momentarily to rest and reverses its direction. What is its value?

In a geiger - marsden experiment. Find the distance of closest approach to the nucleus of a 7.7 me v alpha - particle before it comes momentarily to rest and reverses its direction. (z for gold nucleus = 79) .
