Finding spring constant with electron on end

AI Thread Summary
To find the spring constant using an electron at its end with a frequency of 4.9X10^14 Hz, the mass of the electron is 9.11X10^-31 g. The period can be derived from the frequency, but the challenge lies in determining the displacement (x) needed for the calculation. It is suggested to apply the simple harmonic motion (SHM) formula, focusing on the relationship between frequency and spring constant without considering electrostatic forces. The discussion emphasizes that the electron's charge can be ignored for this calculation, simplifying the process to using the SHM formula to derive the spring constant.

Homework Statement


Calculate the spring constant of a spring with an electron mass at itsend and the frequency 4.9X10^14 Hz. mass of electron: 9.11X10^-31 g


Homework Equations



F=kx
k=mg/x


The Attempt at a Solution


Since i know the frequency, i can get the period, but where i am stuck is how to turn the period into an x value that i can use to determine the value of k. should i be using coulomb's law for this?

It's funny how they used an electron instead of any mass, but since there's no consideration of any electrostatic forces, you can just ignore the electron charge. Just plug in the SHM formula for period/frequency with the given info to find the spring constant.

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}...

Thread 'Struggling to understand the concept of the 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...
