5. (Serway 9th ed., 7-3) In 1990, Walter Arfeuille of Belgium lifted a 281.5-kg object through a distance of 17.1 cm using only
1 answer:
Para resolver este problema es necesario aplicar los conceptos de Fuerza, dados en la segunda Ley de Newton y el concepto de Trabajo, como expresión de la fuerza necesaria para realizar una actividad en una distancia determinada.
El trabajo se define como
W = F*d
Where,
F = Force
d = Distance
At the same time we have that the Force by second's Newton law is equal to
F = mg
Where,
m = mass
g = Gravitational acceleration
PART A) Using our values and replacing we have that
PART B) Using Newton's Second law we have that,

Answer:
q = 2.65 10⁻⁶ C
Explanation:
For this exercise we use Coulomb's law
F =
In this case they indicate that the load is of equal magnitude
q₁ = q₂ = q
the force is attractive because the signs of the charges are opposite
F =
q =
we calculate
q =
q = Ra 7 10-12
q = 2.65 10⁻⁶ C
Answer:
Explanation:
From the question we are told that
Distance b/w plate
P_1 Potential at 7.35
Generally the equation for electric field at a distance is mathematically given as
