Question

With a thunderstorm brewing, an electric field of magnitude 2.0 × 102 newtons/coulomb exists at a certain point in the earth’s atmosphere. If an electron at that point has a charge of -1.6 × 10-19 coulombs, what is the magnitude of the force on the electron as a result of the electric field?
A) 2.0 × 10^-6 newtons
B) 3.2 × 10^-17 newtons
C)5.8 × 10^5 newtons
D)6.4 × 10^-3 newtons
E) 1.7 × 10^4 newtons

Answer 1

(2.0 x 10² N/Coul) x (-1.6 x 10⁻¹⁹ Coul) = -3.2 x 10⁻¹⁷ N

The magnitude is 3.2 x 10⁻¹⁷ Newton.
