How Can I Solve This Electric Field Integral?

AI Thread Summary
The discussion centers on solving a challenging integral related to calculating the electric field above a spherical shell. The integral in question is ∫[(z-Ru)/(z^2+R^2-2zRu)^(3/2)] du, with limits from -1 to 1, where z and R are constants. Participants suggest that the integral can be found in standard physics textbooks or solved using online tools like Wolfram Alpha. The conversation emphasizes persistence in problem-solving and utilizing available resources for assistance. Overall, the integral's complexity is acknowledged, but solutions are deemed accessible through various methods.

Hey guys,

While trying to calculate the electric field above a spherical shell i ran into this integral that i am having some difficulty solving.

∫[(z-Ru)/(z^2+R^2-2zRu)^(3/2)] du

-1 < u < 1

(z and R are known constants)

Can anyone help point me in the right direction? Thx

its easy ...keep trying or if u still dnt gt it dis integration is solved in any std physics book...
 
and if you can't get it , you can solve it by wolfram http://www.wolframalpha.com/input/?i=integral+%28a-b*x%29%2F%28a^2%2Bb^2+-+2*a*b*x%29^%283%2F2%29+dx
 
Do a google search for "the integrator wolfram"
 

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}...
