Answer:

see explanation

Step-by-step explanation:

The area of a rectangle = length × width

To find the width, divide the area by the length

width = $\frac{area}{length}$ = $\frac{3x^2+9x}{3x}$

To simplify divide each term on the numerator by 3x

= $\frac{3x^2}{3x}$ + $\frac{9x}{3x}$ = x + 3 ← width

What force is exerted on a test charge of 3.25 E−5 C, if it is placed in an electric field of magnitude 1.40 E4 N/C? Remember to

marshall27 [118]

Answer:

0.46 newtons

Step-by-step explanation:

For these kinds of problems, you can employ the formula

$E=\dfrac{F}{q}$

where E represents the field in N/C, F represents the force in newtons, and q represents the charge in coulombs. You can therefore set up the following equation:

$1.4\times 10^4 N/C=\dfrac{F}{3.25\times 10^{-5}C} \\\\$

$F=(1.4\times 10^4 N/C) \times (3.25 \times 10^{-5} C)=4.6 \times 10^{-1} N$ (following sig figs)

Hope this helps!
