Question

How do you solve electric field problems?

Answer 1

Things that we absolutely need in order to solve the problems,

1. Apply the Electric field formula given below:
   $E=k\frac{\left|q\right|}{d^2}$
2. Draw the electric field vector.
3. Use $k=9\times {10}^{-9}N{m}^2{C}^{-2}$
4. Convert $d$ to the meter before doing the calculation,
5. The electric field unit is $\frac{N}{C}$.

The electric field is the electric force per unit charge. The direction of an electric field is obtained from the direction in which the force exerts on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

$\overrightarrow{E}=\frac{\overrightarrow{F}}{q}$

The above relation is used to determine the electric field.
