Electric Potential problem, 4 equal charges, different signs, weird shape.

AI Thread Summary
The discussion centers on calculating the total electric potential at a specific location due to four point charges, each with a different sign. The given charge value is 1.96 µC, and the distance between charges is 0.93 m. Participants emphasize the importance of treating electric potential as a scalar quantity rather than a vector, which affects the calculation method. Users are encouraged to share their detailed calculations for better assistance in identifying errors. The homework deadline is approaching, adding urgency to the request for help.

Homework Statement


The drawing shows four point charges. The value of q is 1.96 µC, and the distance d is 0.93 m. Find the total potential at the location P. Assume that the potential of a point charge is zero at infinity.
Image of problem is attached.

Homework Equations



V=kq/r

The Attempt at a Solution



Our attempts at solving this problem included just adding the various vectors, canceling out the negative vectors since they pull in the opposite direction and just using the positive vectors, but neither works. Help? Problem due Tuesday by 11:30pm for homework. Thanks

Hi BATBLady! :wink:

Show us your full calculations, and then we can see what went wrong, and we'll know how to help! :smile:

(btw, potential is a scalar, not a vector)
 

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...
