Question

The strength of the electric field 0.5 m from a 6 µC charge is positive N/C. (Use k = 8.99 × 109 N• and round answer to the nearest whole number.)

Answer 1

according to e2020 the answer is 215760                                                                                            

Answer 2

`2.16 \cdot 10^5 N/C`

Step-by-step explanation:

The strength of the electric field produced by the single charge is given by

`E=(kq)/(r^2)`

where

`k=8.99\cdot 10^9 N m^2 C^(-2)` is the Coulomb's constant

`q = 6 \mu C = 6 \cdot 10^(-6) C` is the charge

`r = 0.5 m` is the distance from the charge at which we want to calculate the field strength

Substituting the numbers into the equation, we find

`E=((8.99\cdot 10^9 )(6 \cdot 10^(-6) C))/((0.5 m)^2)=2.16\cdot 10^5 N/C`
