An electric field of 280000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of -7.9C at this spot?

Respuesta :

The magnitude of the force that acts on a charge of -7.9C at this spot is 2.21 x 10⁶ N.

Explanation:

Electric field is the ratio of force and charge.

Electric field, E = 280000 N/C

Charge, q = -7.9 C

We have

                 [tex]E=\frac{F}{q}\\\\280000=\frac{F}{7.9}\\\\F=280000\times 7.9\\\\F=2.21\times 10^6N[/tex]

The magnitude of the force that acts on a charge of -7.9C at this spot is 2.21 x 10⁶ N.
