(HELP!!! 30 pts if answered right. )What formula gives the strength of an electric field, E, at a distance from a known source charge? E = Startfraction F Subscript e baseline over q times d Endfraction. E = Startfraction k times q over d Endfraction. E = Startfraction k times q over d Superscript 2 baseline Endfraction. E = Startfraction F Subscript e baseline over d Endfraction.

Answer:

[tex]E=\frac{k\,Q}{d^2}[/tex]

Explanation:

The strength of an electric field E produced by a single charge Q at a distance d from it is given by the formula: [tex]E=\frac{k\,Q}{d^2}[/tex], where K represents the Coulomb constant.

Since the electric field E is derived from the Coulomb Force per unit charge using a positive test charge, the field's units will be in units of Newtons/Coulomb, and be the formula for the Coulomb electric force between to charges (Q1 and Q2),

[tex]F_C=k\frac{Q_1\,Q_2}{d^2}[/tex]

but modified with only one charge showing in the numerator of the expression.
