Find the magnitude and direction of an electric field that exerts a 4.80×10−17N westward force on an electron. (b) What magnitude and direction force does this field exert on a proton?

Respuesta :

Explanation:

(a) E = F/q

E = 4.8×10^-17/1.6×10^-19

E = 300 N/C

(b) same magnitude of electric field is exerted on proton

a). The magnitude along with the direction of the electric field releasing westward force of [tex]4.80[/tex] × [tex]10^{-17}[/tex] N would be:

[tex]3[/tex] × [tex]10^{-36}[/tex] N/C is Eastward Direction

b). The magnitude along with the force of the direction that this field releases on proton would be:

[tex]4.8[/tex] × [tex]10^{17} N[/tex] in Eastward Direction

Electric Field

a). Given that,

Force [tex]=[/tex] [tex]4.80[/tex] × [tex]10^{-17}[/tex] N

As we know,

Force [tex]=[/tex] Charge × Electric Field

So,

∵ Electric Field [tex]= Force/Charge[/tex]

[tex]= 4.8[/tex] × [tex]10^{17}[/tex])[tex]/(1.6[/tex] × [tex]10^{-19}[/tex][tex])[/tex]

[tex]= 3[/tex] × [tex]10^{36}N/C[/tex]

The direction of the field would be opposite i.e. Eastward direction due to the field carrying a -ve charge.

b). The magnitude carried by the force working on the proton would be the same with an opposite direction due to +ve charge.

∵ Force  [tex]=[/tex] [tex]4.80[/tex] × [tex]10^{-17}[/tex] N in Eastward direction.
