Electric Force: Solving the Mystery of Coulomb's Law

AI Thread Summary
To solve the problem regarding the electric force in a hydrogen atom, Coulomb's law can be applied since both the electron and proton are charged particles. The electric force can be calculated using the formula F = k * |q1 * q2| / r^2, where k is Coulomb's constant, q1 and q2 are the charges of the electron and proton, and r is the distance between them. For the electron's orbital speed, the centripetal force must equal the electric force, leading to the equation v = sqrt(F/m), where F is the electric force and m is the mass of the electron. The centripetal acceleration can then be determined using the formula a = v^2/r. Understanding these relationships is crucial for solving the problem effectively.

Electric Force!

I am uncertain how to apply Coulomb's law, if this is even the right way to go about it, to this problem on Electric Force because I am not given two charges. The question is: On average, the electron and proton in a hydrogen atom are separated by a distance of 5.3x10^-11 m. Assuming the orbit of the electron to be circular, (a) what is the electric force on the electron? () What is the electron's orbital speed? (c) What is the magnitude of the electron's centripetal acceleration in units of q?Thank you for your help

Of course you are given two charges. Both the proton and electron are charged particles. (They have the same magnitude of charge, but different signs; look up the charge on the electron.)
 
What is the equation for the Columb force? What is the equation for centriptal acceleration in uniform circular motion?
 

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 '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...
