1. Una carga eléctrica de 5*10-6 C genera un campo eléctrico a su alrededor. Calcula la intensidad de este campo a una distancia
Jlenok [28]

Answer:

La intensidad del campo eléctrico es 70312.5 \frac{N}{C}.

Explanation:

La perturbación que crea en torno a ella una carga eléctrica se representa mediante un vector denominado campo eléctrico.

Se dice que un campo eléctrico es uniforme en una región del espacio cuando la intensidad de dicho campo eléctrico es el mismo en todos los puntos de dicha región.

El campo eléctrico E creado por la carga puntual q en un punto cualquiera P se define como:

E=k*\frac{q}{r^{2} }

donde q es la carga creadora del campo, k es la constante electrostática y r es la distancia desde la carga fuente al punto P.

En este caso, los datos son:

  • k= 9*10⁹ \frac{N*m^{2} }{C^{2} }
  • q= 5*10⁻⁶ C
  • r= 0.8 m

Reemplazando:

E=9*10^{9}\frac{N*m^{2} }{C^{2} }  *\frac{5*10^{-6} C}{(0.8 m)^{2} }

Resolviendo:

E= 70312.5 \frac{N}{C}

<em><u>La intensidad del campo eléctrico es 70312.5 </u></em>\frac{N}{C}<em><u>.</u></em>

Sheila uses a 45N force on her bowling ball across a 15m lane. What work did she do on the bowling ball? Show your work.​
Maurinko [17]

Answer:

675J

Explanation:

Given parameters:

Force  = 45N

Distance  = 15m

Unknown:

Work done by Sheila  = ?

Solution:

Work done by a body is the amount of force applied to make a body move through a distance;

         Work done  = Force x distance

 Now;

          Work done  = 45 x 15  = 675J
