AI Thread Summary
The discussion revolves around a confusing question regarding vectors A, B, and C, specifically whether A and B are perpendicular based on the given expressions. Participants express uncertainty about the phrasing of the question, suggesting it may contain a typo or be poorly constructed. There is a consensus that the notation is inconsistent, with vector notation used in one part and scalar notation in another. Some participants speculate that the intended answer might be false due to the ambiguity. Overall, the clarity of the question remains a significant concern among contributors.

Homework Statement



If A-B-C (vectors) and A^2+ B^2+ c^2 where X is the magnitude of X(vector) for X-A,B,C, then the vectors A and B are perpendicular to each other. (True or false?)

The Attempt at a Solution



Honestly, I never post anything unless I have it at least halfway solved. But I'm completely confused by this question. Can anyone help me?

i didnt get the question...kindly phrase it again!
 
Ahhh...so it's not just me? Maybe there was a typo in this sheet, but that's how the question was phrased. I suppose they mean X is the magnitude of X(vector) for X-A, X-B, and X-C. The first expression (A-B-C) is in vector notation, but the second one (A^2 + B^2 + C^2) is not. I'm not sure if that clarifies anything. Maybe it's just a poorly written question?

The question does not make sense to me either. However, perhaps this is deliberate and the answer is false? :smile:
 

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 '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 .
