Question

Consider a square with side 54.1 cm. Calculate the electric field at the center if one corner is occupied by a +41.9 µC charge and the other three are occupied by -27.3 µC charges.

Answer 1

Hi! Do you have any idea where to start? Have you attempted a solution?

Answer 2

yea i did but i cant seem to get the right answer

Answer 3

Let me see what I get, then...

Answer 4

Ar you using Coulomb's constant as \(8.987\times 10^9\left[\dfrac{\rm{N\bullet m^2}}{\rm{C^2}}\right]\)?

Answer 5

yea E=k*q/r^2

Answer 6

where r = sqrt2*54.1

Answer 7

And you used \(r=\sqrt{54.1^2+54.1^2\ }\)?

Answer 8

\(\implies r^2=2(54.1)^2=5854\ \rm m^2\)
