Example 8: Coulomb force in electrostatics is given by the equation Fc = k
r2 '
where k is the
%3D
electrostatic constant and is k = where e, is the permittivity of free space with units
A².s+.kg1•m-³. Furthermore q,and q2 represent charges with units A·s, and r is distance with
units m. What units does this tell us for force Fc? Note that A is for amps

Expert Solution

Step 1

The expression for the electrostatic force is as follows:

$F_{C} = \frac{1}{4 π ε_{0}} \frac{q_{1} q_{2}}{r^{2}}$

The given units are as follows:

$\begin{array}{l} ε_{0} = (A^{2} \cdot s^{4} \cdot {kg}^{- 1} \cdot m^{- 3}) \\ q = (A \cdot s) \\ r = (m) \end{array}$
