What is distance of closest approach?

When an alpha particle is projected towards a nucleus, it retards due to repulsion from the nucleus because both are positively charged. A distance from the nucleus may exist where the alpha particle stops and then rebounds back due to a very strong repulsion from the nucleus. The distance up to which alpha particle comes closer to the nucleus is called the distance of the closest approach. Its value can be determined by the conservation of energy principle.

How to Calculate Distance of closest approach?

Distance of closest approach calculator uses Distance of closest approach=([Coulomb]*4*Atomic number*([Charge-e]^2))/([Atomic-m]*(Velocity of alpha particle^2)) to calculate the Distance of closest approach, The Distance of closest approach formula is defined as is the distance to which an alpha particle comes closer to the nucleus. Distance of closest approach and is denoted by r0 symbol.

How to calculate Distance of closest approach using this online calculator? To use this online calculator for Distance of closest approach, enter Atomic number (Z) and Velocity of alpha particle (v) and hit the calculate button. Here is how the Distance of closest approach calculation can be explained with given input values -> 23.53663 = ([Coulomb]*4*17*([Charge-e]^2))/([Atomic-m]*(6.34^2)).

FAQ

What is Distance of closest approach?
The Distance of closest approach formula is defined as is the distance to which an alpha particle comes closer to the nucleus and is represented as r0=([Coulomb]*4*Z*([Charge-e]^2))/([Atomic-m]*(v^2)) or Distance of closest approach=([Coulomb]*4*Atomic number*([Charge-e]^2))/([Atomic-m]*(Velocity of alpha particle^2)). Atomic number is the number of protons present inside the nucleus of an atom of an element and Velocity of alpha particle is a vector quantity (it has both magnitude and direction), and is the time rate of change of position (of a particle).
How to calculate Distance of closest approach?
The Distance of closest approach formula is defined as is the distance to which an alpha particle comes closer to the nucleus is calculated using Distance of closest approach=([Coulomb]*4*Atomic number*([Charge-e]^2))/([Atomic-m]*(Velocity of alpha particle^2)). To calculate Distance of closest approach, you need Atomic number (Z) and Velocity of alpha particle (v). With our tool, you need to enter the respective value for Atomic number and Velocity of alpha particle and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
