Parallel plate capacitor book problem

AI Thread Summary
To solve the problem of the parallel plate capacitor, start by establishing the kinematics equations for both the electron and proton, considering their initial positions and directions of motion. The electron, starting from the negative plate, will accelerate towards the positive plate, while the proton moves from the positive plate towards the negative plate. Calculate the acceleration of each particle using the electric field generated between the plates, given by E = λ/ε₀. By determining the time it takes for both particles to meet, you can find the distance from the negative plate where they pass each other. This approach will lead to the solution of the problem effectively.

Homework Statement



Two parallel plates 0.700 cm apart are equally and oppositely charged. An electron is released from rest at the surface of the negative plate and simultaneously a proton is released from rest at the surface of the positive plate. How far from the negative plate is the point at which the electron and proton pass each other?

Homework Equations



E = \lambda/\epsilon_{0}

Begin by writing the appropriate kinematics equations for each particle. One of the particles starts at zero and the other starts at 0.700 cm and moves towards zero. Can you find the acceleration of each particle?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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 hanging 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...
