# Electric Field Isolines

APPH12-FGJN0U

Isolines in an electric field are constructed to located points of equal electric field strength.

How far from the center of a charged sphere (with a radius of $0.15\text{ cm}$) is the isoline representing $260\text{ N/C}$ if the charge on the sphere is $7.5\times10^{-9}\text{ C}$?

A

$51\text{ cm}$

B

$26\text{ cm}$

C

$0.51\text{ cm}$

D

$0.26\text{ cm}$
