AI Thread Summary
To determine the speed at which a stone must move horizontally in a uniform magnetic field of 1.7T without vertical deviation, it's essential to understand the forces acting on the stone. The equations provided, such as (9.8)(mass of rock)=QvB and mv^2/r=QvB, are not applicable in this context since the stone is not experiencing circular motion or vertical forces. Clarification on the stone's charge and the orientation of the magnetic field is also necessary, as these factors influence the motion. The discussion highlights the need for a clear understanding of the magnetic field's direction and the parameters involved in the equations. Accurate interpretation of these elements is crucial for solving the problem effectively.

A stone is moving constantly in a horizontal motion in a uniform magnetic field in the direction pointing into the page. The field's strength is 1.7T. How fast does the stone have to move in order for it to remain moving horizontally without any vertical deviation?

For this quesion, using (9.8)(mass of rock)=QvB doesn't work because there's no vertical deviation. I also tried to do mv^2/r=QvB, but since it is moving horizontally and not in a circle, that doesn't work either. Can someone help me with this question please.

Is that stone charged? What is its charge? Is the page vertical?

Do you know the meaning of the letters in the equations you cited? Is any of them include "vertical deviation"?

yeah i know the letters...the charge is -0.010C, my page is not vertical...
 
What is the direction of the magnetic field? You said, it is pointing into the page. Which page? Show a picture.

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...
