Angle made by electric field lines

AI Thread Summary
The discussion focuses on determining the angle y at which an electric field line enters a negative charge -q2, given that it emerges from a positive charge +q1 at an angle x. The initial assumption was that the charges q1 and q2 are equal, simplifying the problem through symmetry. However, the user realizes that the charges are not equal, complicating the calculation. They seek hints or guidance from others to solve the problem effectively. The conversation highlights the challenges of working with unequal charges in electric field line analysis.

Homework Statement


an electric field line emerges from a positive point charge +q1 at an angle x to the straight line joining it to a negative charge -q2.at what angle y will the field line enter the charge -q2?

Homework Equations





The Attempt at a Solution


sin(y/2)=sin(x/2)(q1/q2)^1/2

Sorry, I was assuming q1 and q2 are equal, in which case the answer is obvious from symmetry. But it appears that that are NOT equal and I don't know how to deal with that.
 
Hi guys,
I have the same problem, please give me hints for solving the question, tnx a lot :wink:
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
