Tension from string upon a rock

AI Thread Summary
The discussion revolves around calculating the tension in a string connecting two 3 kg masses, one at 0.5m and the other at 1.5m, while they are swung at 2 revolutions per second. The key question is the relationship between the tension experienced by the mass further from the hand and the tension near the hand. A hint suggests that proportions can be used to solve the problem without needing to determine the exact centripetal forces. Clarification is sought regarding whether the masses are connected directly or in a head-to-tail manner. Understanding the centripetal force acting on each mass at their respective radii is crucial for solving the problem.

Homework Statement


Two 3 kg masses are attached to a string at r1=.5m and r2=1.5m from where the string is held in your hand. You swing them around together at 2 revolutions per second, each of them. The tension holding mass 2 (the distant part of the string) is what fraction of the tension near your hand?


Homework Equations



No Idea.

The Attempt at a Solution


No idea how to figure this problem out.

Welcome to PF.

Are the blocks tied together in some way?

Like head to tail?
 
Thanks.

That is all the information I received on the question.
A hint that was given was:[Hint: you can work in proportions without having to numerically solve for either of the centripetal forces required on the two masses]
 
I read it more carefully. Apparently it is tied to the same string at each of the 2 radii.

What is the force of a single mass at some radius rotating in a circle?

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...
