Question

What is the strength of an electric field 0.2 m from a 1.56 x 10-6 C charge?

Answer 1

Solution given:

strength of electric field [E]:?

distance[d]:0.2m

charge[Q]=
`1.56×10^(-6) C`

we have

E =K
`(Q)/(r²)`

E=
`9×10^(9) C`
`(1.56×10^-6 C)/(0.2²)`

E=
`3.51×10^(5)`V/m

strength of electric field :
`3.51×10^(5)`V/m
