Electric Force Acting on Alpha Particle and Gold Nucleus

AI Thread Summary
The discussion focuses on calculating the electrical force acting on an alpha particle with a charge of +2.0e when it is 2.0 x 10^-14 m away from a gold nucleus with a charge of +79e. The calculated force is 91 N, but the user seeks clarification on the steps to arrive at this answer. Participants emphasize the importance of using Coulomb's law for the calculation. Additionally, there is a reminder to show working steps for homework questions to facilitate assistance. The conversation highlights the need for clarity in problem-solving and communication in academic forums.

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...

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 .
