What Is the Electric Field Perpendicular to a Uniformly Charged Rod?

AI Thread Summary
To determine the electric field perpendicular to a uniformly charged rod, the problem involves a rod of length 0.1m with a linear charge density of 3C/m, and the electric field is to be calculated at a point 1m away from the rod. The approach requires using the principle of superposition and integrating the contributions from each infinitesimal segment of the rod. The integration setup mentioned is incorrect; it should involve the correct expression for the electric field due to a line charge, specifically integrating from 0 to 0.05m (half the length of the rod) and ensuring the correct power of (L^2 + d^2) is used in the denominator. Properly applying these principles will yield the electric field at the specified point.

Homework Statement


A rod of length 0.1m has a uniform linear charge density of 3C/m. Determine the Electric field at a point d=P located at a perpendicular distance 1m along a line of symmetry of the rod.


The Attempt at a Solution


I know i have to use super position and integrate but I don't think I'm using the right integration.

I was trying 2\lambdaL\oint\frac{ddl}{ (L^2 + d^2)^3/2}
 
Physics news on Phys.org
it should be (L^2 + d^2) to the 3/2 power. and it is integrated from 0 to 1/2. and lamba is the linear charge density, L is length of rod, d is distance normal to rod
 

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}...
