Calculating Electric Field and Force in Singly Ionized Helium Atom

AI Thread Summary
The discussion centers on calculating the electric field strength and electrostatic force in a singly ionized helium atom, which has two protons in its nucleus. The key question is whether to use the charge of one proton or the total charge of the nucleus, which is +2e, for the calculations. It is clarified that the net charge of +2e should be used for determining the electric field strength at the location of the remaining electron. The conversation confirms the understanding of using the net charge for the calculations. Overall, the focus is on applying the correct charge value in the context of the problem.

Homework Statement


the helium atom contains two protons in its nucleus. when helium is singly ionized, one of its two electrons is completely removed. the remaining electron orbits the nucleus at a radius of 2.65*10^-11
a) what is the electric field strength created at the location of the electron by the nucleus?
b)what is the electrostatic force acting on the electron?

Homework Equations





The Attempt at a Solution


Just wondering , the question said the helium atom contains two protons, the charge of one proton is +1.60*10^-19, for a) do i multiply by 2? or the value 1.60*10^-19C stay the same?
 
Physics news on Phys.org
Net charge in the nucleus is +2e, where e is the charge on the proton.
 
is that mean I have to use the net charge for a)?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
