Question

An example question and answer on an electric field acting on a charge

Answer 1

Step-by-step explanation

a small charge q= 7.0 mC is found in a uniform E-fie E=3.2 N/C, determine the force on the charge

to solve this we need to use the expression:

`\begin{gathered} F=qE \\ \text{where F is the force} \\ q\text{ is the charge} \\ E\text{ is the electric field} \end{gathered}`

so

Let

`\begin{gathered} q=7.0\text{ mC} \\ E=3.2\text{ N/C} \end{gathered}`

replace

`\begin{gathered} F=qE \\ F=7.0mC\cdot\text{ 3.2 N/C} \\ F=22.4\text{ Newtons} \end{gathered}`

so, the force is 22.4 Newtons

I hope this helps you
