A proton and an electron in a hydrogen atom are separated by a distance of 5.3 x 10^-11 m. The magnitude and direction of electric field set up by the proton at the position of the electron is:

5.1 x10^11 N/C away from the proton

5.1 x10^11 N/C toward the proton

5.1 x10^10 N/C toward the proton

5.1 x10^10 N/C away from the proton

shamim · Answer

Do u know the direction of electric field for a positive charge is outward?

shamim · Answer

And tge direction of electric field for a negative charge is inward???!!

anonymous · Answer

I think I got it. I got 5.1 x10^10 N/C toward the proton.

anonymous · Answer

Is that right?

shamim · Answer

Required formula for electric field is
E=(1/4*pi*afcylon not)q/r^2

shamim · Answer

Proton has positive charge. Right????

anonymous · Answer

Yes

anonymous · Answer

I think my answer is right though.

shamim · Answer

So its electric field will b outward

shamim · Answer

So toward the proton is wrong!!!!

anonymous · Answer

Ah, okay. I see.

anonymous · Answer

So it's away from the proton.

shamim · Answer

First option is right!!!

anonymous · Answer

Thanks!
