AI Thread Summary
An object with a net charge of 18 µC is placed in a uniform electric field of 597 N/C and is floating, indicating that the upward electric force equals the downward gravitational force. The discussion highlights the need to equate these forces to find the mass of the object. The upward force is due to the electric field, while the downward force is the weight of the object. The solution involves setting the electric force equal to the gravitational force to solve for mass. The participant successfully resolved the problem after clarifying the forces involved.

Homework Statement



An object with a net charge of 18 µC is placed in a uniform electric field of 597 N/C, directed vertically. What is the mass of the object if it floats in the electric field?

Homework Equations



F=kq1q2/r^2

The Attempt at a Solution


dont understand at all
 
Physics news on Phys.org
Ok, start with the first statement, they said the electric field is directed upwards. So what force is upwards?

Naturally what force will be exerted on the mass downwards?

Now put these two equal to each other.
 
thank you i solved it
 

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...
