Find the location where the electric field is zero if the +7.0-wC charge is at the origin and the -3.5 pC charge is at x 0.14 m. Need Help? LReadH Two positively charged spheres are shown n the figure below. Sphere 1 has twice as much charge as sphere 2. If q 2.60 nC. 0.200 m, and y 1.10 m, what is the electr field at point A?

Explanation / Answer

Enet = 0

[k(7) / x2] - [k(3.5) / (x - 0.14)2] = 0

(x - 0.14)2 * 7 = 3.5 x2

7 x2 + 0.1372 - 1.96 x = 3.5 x2

3.5 x2 -1.96 x + 0.1372 = 0

x = 0.477 m
