What is the magnitude of the force on a calcium ion

AI Thread Summary
The discussion centers on calculating the force on a calcium ion in a cell membrane with an electric field strength of 1.0x10^7 N/C. The relevant equation is F = Eq, where E is the electric field and q is the charge of the ion. The user initially assumed the charge of the calcium ion (+e) to be approximately 1, leading to an incorrect force calculation. Clarification is sought on the value of +e, which is indeed equal to the elementary charge of approximately 1.6x10^-19 C. Understanding this value is crucial for accurately determining the force acting on the calcium ion.

Homework Statement


Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.0x10^7 N/C. What is the magnitude of the force on a calcium ion with charge +e?


Homework Equations


E = F/q > F = Eq


The Attempt at a Solution


Well, I thought that +e = ~1, so F = 1.0x10^7(1)
So, F would equal 1.0x10^7, but that is not correct.

Can anyone help me?

What is +e in C? F=Eq is correct.
 
Is +e the same as e-? Because 1 e- is equal to 1.6x10^-19 C, right?
So, is that the same for +e?
 

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...
