Electric potential at the center of meter stick

AI Thread Summary
To find the electric potential at the center of a meter stick with two 3.00-μC charges at each end, the formula V = kq/r is used, where k is Coulomb's constant, q is the charge, and r is the distance from the charge to the point of interest. The distance r for each charge to the center is 0.5 m. The potential from both charges is calculated by summing their contributions, factoring out k/r as they are equal. The user is experiencing a discrepancy in their calculations, suspecting a possible calculator error. The correct potential can be confirmed by re-evaluating the calculations with the given parameters.

Two 3.00-μC charges are at the ends of a meter stick. Find the electrical potential for the center of the meter stick.



V=kq/r



I just want to confirm my answer here. What I did is solve this for both charges in the equation above using r = 0.5m q= 3.00 uC. So I factored out k/r since they were the same for both charges, summed the charges, and then multiplied by k/r. My number isn't coming out correct for some reason and I believe it may just be calculator error. Thanks!

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'

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...
