Finding Focal Lengths of Microscope Lenses

AI Thread Summary
To find the focal lengths of microscope lenses, the magnification formula M = -q / p is relevant, where q is the image distance and p is the object distance. The total magnification of the microscope is the product of the magnifications of the objective and eyepiece lenses, which in this case is 50 times for the objective and 10 times for the eyepiece, resulting in a total magnification of 500. The length of the microscope tube is 25.0 cm, which can be used to relate the distances for the two lenses. Understanding the relationship between the focal lengths and the distances involved is crucial for solving the problem. Proper application of these principles will lead to the determination of the focal lengths of the lenses.

Can someone tell me what sort of equation I would use for this question, I can't use the magnification as I have two unknowns. At least I don't know how to apply the magnification equation to this question.

A microscope is made in a tube 25.0cm long. It magnifies 5.00 x 10 to the 2 times, 50.0 times by the objective lens and 10 times by the eyepiece. What is the focal length of the two lenses?

What do you need to get greater magnification, a wider objective lens? :bugeye:
 
magnification is given by the eq. M = -q / p

see if that helps
 

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 '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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
