Question

what is the electric feild strength 5.0 cm from 6.6muC charge?(answer with two sig figs. For scientific notation answer like 2.3E-4.)

Answer 1

Given data

*The given distance is r = 5.0 cm = 0.05 m

*The given charge is

`q=6.6\mu C=6.6*10^(-6)\text{ C}`

The formula for the electric field strength is given as

`E=(kq)/(r)`

*Here k is the Coulomb constant

Substitute the values in the above expression as

`\begin{gathered} E=((9*10^9)(6.6*10^(-6)))/(0.05) \\ =1.18*10^6\text{ N/C} \end{gathered}`
