AI Thread Summary
The discussion focuses on calculating the net force and electric field acting on charge 1 in a given charge distribution. Participants emphasize the use of the electrostatic force equation, F = (k)(Q1)(Q2)/d^2, to determine the force. There is a reminder that the force is a vector quantity, indicating the importance of direction in calculations. Some users point out that additional information is needed to complete the calculations accurately. The conversation highlights the need for careful consideration of both magnitude and direction when analyzing electric forces.

You have the equation for electrostatic force. Apply it to the given setup.
 
F = (2)(+2 x 10^-5)(-3 x 10^-5)
Is that right?

Some things are missing from that equation. Don't forget that force is a vector.
 

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...
