TSny said:Your work looks correct assuming that they just want the magnitude of the potential difference. If they want the potential difference as ΔV = Vfinal - Vinitial, then you should consider the sign of the potential difference.
The potential difference of a helium nucleus refers to the difference in electrical potential energy between two points on the surface of a helium nucleus. It is measured in volts (V) and is dependent on the charge and distance of the particles involved.
The potential difference of a helium nucleus can be calculated using the formula V = kQ/r, where V is the potential difference, k is the Coulomb constant (9x10^9 Nm^2/C^2), Q is the charge of the nucleus, and r is the distance between the two points on the surface of the nucleus.
The potential difference of a helium nucleus is important because it affects the behavior of charged particles in its vicinity. It determines the strength of the electric field and can influence the movement and interactions of particles in a system.
The potential difference of a helium nucleus is unique to helium due to its specific charge and distance between its particles. Other atoms may have different potential differences depending on their composition and structure.
Yes, the potential difference of a helium nucleus can change if either the charge or distance between the particles changes. It can also change if an external electric field is applied to the nucleus, altering the strength of the electric field and therefore the potential difference.
