120 miles because of a car is going at 60 miles per 1 hour, 2 hours would result in 120 miles
Answer:
0.9 N
Explanation:
The electric force acting on a charge is given by:

where
q is the magnitude of the charge
E is the strength of the electric field
In this problem, we have
is the charge
is the strength of the electric field
Substituting into the equation, we find

Answer: E = 7,490.6 N/C
Explanation:
If we have a field E, and a particle with a charge q, the force that the particle experiences is:
F = E*q
In this case, we know that the force is:
F = 1.2*10^(-15) N
And we know that the particle is a proton, where the charge of a proton is:
q = 1.602*10^(-19) C
Then we can replace these two values in the equation to get:
1.2*10^(-15) N = E*1.602*10^(-19) C
We just need to isolate E.
(1.2*10^(-15) N)/(1.602*10^(-19) C) = E
7,490.6 N/C = E
That is the strength of the electric field.
