Answer:
1. 5.12068 × 1011 N/C away from the proton
Explanation:
The electric field produced by a single point charge is given by:
where
k is the Coulomb's constant
q is the magnitude of the charge
r is the distance from the charge
In this problem, we have:
is the charge of the proton
is the distance at which we want to calculate the field
is the Coulomb's constant
Substituting into the formula,
And the direction of the electric field produced by a positive charge is away from the charge, so the correct answer is
1. 5.12068 × 1011 N/C away from the proton
