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.

Homework Statement


an alpha particle (charge=+2.0e) is sent at high speed toward a gold nuclues Charge= +79e. What is the electrical force acting on the alpha particle when it is 2.0 times 10^ -14m away from the gold nucleus


Homework Equations





The Attempt at a Solution



its 91 N but i need the steps of how i got the answer

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
