Question

What is the electric force between à -0.02 C charge and a 0.03 C charge separated by 2.4meters?

Answer 1

Given:

The charges;

q₁=-0.02 C

q₂=0.03 C

The separation between the charges, r=2.4 m

To find:

The electric force between the charges.

Step-by-step explanation:

From Coulomb's law,

`F=(k|q_1||q_2|)/(r^2)`

Where k is the Coulomb's constant.

On substituting the known values,

`\begin{gathered} F=(9*10^9*0.02*0.03)/(2.4^2) \\ =937.5*10^3\text{ N} \\ =937.5\text{ kN} \end{gathered}`

Final answer:

The electric force between the charges is 937.5 kN.
