Acceleration and Kinetic Energy

AI Thread Summary
The discussion revolves around understanding the relationship between acceleration, kinetic energy, and the dynamics of a charged particle approaching a nucleus. Key equations mentioned include acceleration (a = F/m) and kinetic energy (Ek = 1/2 mv^2). Participants express confusion about determining velocity from kinetic energy and the concept of the point of closest approach, questioning where kinetic energy is maximized. There is a critical discussion on whether the force between two positive charges is attractive or repulsive, impacting the particle's motion. The conversation highlights the complexities of energy transformation and motion in electrostatic interactions.

Not exactly sure how to go through with this..
I tried finding velocity with the given kinetic energy, but am unsure what to do next.
 
Physics news on Phys.org
What has happened to the kinetic energy at the point of closest approach? Where is the point of closest approach?
 
Um, the kinetic energy is at it's maximum when it's approaching the nuclues?

Wait.. so is the kinetic energy given to me, is the Ek at the beginning I believe. Not sure how that'll help me though.
 
How fast is the particle moving when at its closest to the nucleus? What has been the change in KE? Where has the energy gone? Can you determine the distance of closest approach?

Are you sure about that? You have a positive charge approaching another positive charge? Is the force attractive or repulsive?
 

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}...
