Potential difference in an electron

AI Thread Summary
The discussion revolves around calculating the potential difference between two plates given that an electron gains 3.01e-16 J of kinetic energy. Using the formula V = W/q, where W is the work done and q is the charge of the electron, the potential difference is calculated to be -1881.25 V. Participants question the significance of this potential difference and its relation to the electron's velocity between the plates. The conversation highlights the importance of understanding the relationship between energy, charge, and potential difference in electric fields. The need for velocity in this context is also explored, indicating its relevance in further calculations.

Homework Statement



An electron acquires 3.01e-16 J of kinetic energy when it is accelerated by an electric field from plate A to plate B. What is the potential difference between the plates?
_____V

Homework Equations



- (Wba / q ) = V

The Attempt at a Solution



- (3.01e-16 / 1.6e-19) = V
V = -1881.25

What does the product of the charge of the electron and the pd of the plates give you?
 
would those give me the velocity between the two plates?
 
Why do you need the velocity for?
 

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 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
