Showing that the P(r) is maximum at r=a_0/Z

AI Thread Summary
The discussion revolves around maximizing the function P(r) at the point r=a_0/Z. A participant initially attempted to integrate the function over all values of r, leading to a messy and divergent result. Other contributors pointed out that the goal is to maximize P(r) directly, rather than integrating it. This clarification helped the original poster understand the correct approach to the problem. The conversation emphasizes the importance of focusing on the function itself rather than its integral for finding the maximum.

The Attempt at a Solution


I tried to integrate (7-32) over all values of r (i.e., from negative infinity to positive infinity) and set it equal to 1, but the result was too messy and was divergent. Am I making the right approach?

Why do you want to integrate? How do you normally find the maximum of a function?

Further to PeroK's comment, you are asked to maximise P(r), not ∫P(r).dr.

To PeroK and haruspex...thank you for the help! It makes perfect sense now. :smile:
 
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}...
