Question

A point charge is placed 100 m from a 6uC charge generating an electric field. What is the strength of the electric

field on the point charge? (Round to the nearest whole number.)

Answer 1

5.4 NC⁻¹

Step-by-step explanation:

Electric field strength is a quantitative expression of the intensity of an electric field at a particular location.

The standard unit - volt per meter (v/m).

• Any electrically charged object produces an electric field. This field has an effect on other charged objects.
• The field strength at a particular distance from an object is directly proportional to the electric charge, in coulombs, on that object.
• The field strength is inversely proportional to the distance from a charged object.

Therefore we can state the above points as a equation as follows

`E=k(Q)/(r^(2) ) \\ k = (1)/(4*pi*e ) = 9*10^(9)mF^(-1) E=9*10^(9)*(6*10^(-6))/(100^(2) )\\E = 5.4 NC^(-1)`
