Answer:
Explanation:
The electric force exerted on a charge due to an electric field is given by:
where
q is the magnitude of the charge
F is the magnitude of the force
E is the magnitude of the electric field
In this problem, we have:
is the charge
is the magnitude of the force
using these data and re-arranging the equation, we can calculate the magnitude of the electric field:
Isn't velocity Distance over time? if the degree isn't adding resistance it should be 4000 ÷ 20 which gives you 200mps ("per second") which is the velocity without resistance.
The proton would be 2 and d a part of 1 then calculate that hope this helped
