Answer:
F = 3.6 10⁶ N
Explanation:
The expression for the electric force is
F = ![k \ \frac{q_1 q_2}{r^2}](https://tex.z-dn.net/?f=k%20%5C%20%5Cfrac%7Bq_1%20q_2%7D%7Br%5E2%7D)
in this case it indicates that the charge q1 is doubled
q₁ = 2 3 10⁻³ C
q₁ = 6 10⁻³ C
let's reduce the magnitudes to the SI system
q₂ = 6 10⁻³ C
r = 0.3 m
let's calculate
F = 9 10⁹ 6 10⁻³ 6 10⁻³ / 0.3²
F = 3.6 10⁶ N
Answer:
Explanation:
Convert the mass to kg:
375g = 375/1000kg = 0.375kg
F = ma
-20 = 0.375a
a = -20/0.375
a = -53
The object is accelerating at 53m/s/s backwards assuming that the forward motion is positive.
