Answer:
Explanation:
Force on electron in an electric field E = eE where E is electric field .
acceleration = eE / m where m is mass of electron .
Putting the values
4 x 10⁶ = 1.6 x 10⁻¹⁹ x E / 9.1 x 10⁻³¹
E = 22.75 x 10⁻⁶ N/C
The direction of electric field will be towards west ( opposite to east )
because of negative charge on electron .
Answer:
"C" I think....
Explanation:
I am really sorry if I am wrong, but if right, I hope this helps!
Atomic Number = amount of protons. Atomic mass = protons (7) and neutrons (8)
Electrons will be the protons - any charge the isotope has. For example, a +2 charge would make the electrons 7- (+2) = 5. A -2 charge would be electrons 7 - (-2) = 9
True IF the engine is 25% efficient. False otherwise.
