Vector Perpendicular to Two Other Vectors

AI Thread Summary
To find a vector that is perpendicular to two given vectors using the dot product, set up equations where the dot product of the unknown vector with each of the known vectors equals zero. This results in two equations with three variables. While the cross product is a more straightforward method to find a perpendicular vector, the focus here is on using the dot product. A deeper understanding of vector operations is recommended to solve the problem effectively. Clarifications on the dot product approach can be sought if needed.

Homework Statement



There are two known vectors (you can make up any two, the question gives them but I don't know what they were) and I need to find a vector that is perpendicular to both of them.

Homework Equations



Dot Product

The Attempt at a Solution



Getting two equations with three variables each for the dot product equal to zero.

You need to go back to your study of vectors more closely.
Besides "dot product", there is another kind of product, the "cross product". I suggest you look it up. If you still have any queries pertaining to it, then feel free to come back here.
 
Sorry I failed to mention that I can only use the Dot product to answer this. With the cross product it wouldn't take much effort at all to answer this question, the trick I'm having trouble with is doing it with the dot product.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
