Final answer:
To determine the electric field strength, we can rearrange the formula as: E = F/q.
Step-by-step explanation:
The motion of an electron in an electric field can be analyzed using the principles of electric force and acceleration. The electric force experienced by a charged particle is given by the equation: F = qE, where F is the force, q is the charge of the electron, and E is the electric field. In this case, we know the force experienced by the electron, but the electric field strength (E) is yet to be determined.
To determine the electric field strength, we can rearrange the formula as: E = F/q. Substituting the given values, we find that E = (1.40 x 10^-16 N) / (1.6 x 10^-19 C) = 8.75 x 10^2 N/C.
Therefore, the electric field strength is 8.75 x 10^2 N/C.
