AI Thread Summary

To find the electric field E(x,y) for a dipole charge of +/- Q and length d oriented along the y-axis, one must start by understanding the dipole moment, which is defined as p = Qd. The electric field can be derived using the formula E = (1/4πε₀) * [2p/(r^3)] for points along the axis of the dipole and E = (1/4πε₀) * [p/(r^3)] for points perpendicular to the dipole axis. The setup requires determining the position vector and calculating the contributions from both charges at a point in the field. Proper vector addition and consideration of symmetry are crucial in solving the problem. This approach will lead to the general expression for the electric field of the dipole.

Help With Dipoles!

I need some help on a question..how to set it up and solve it. Here is the question:

Find the general expression for the electric field E(x,y) for a dipole charge +/- Q and length d oriented along the y-axis and symmetric about the x-axis.

Thank you.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
