Auniform electric field e=15 n/c points downwards. a particle with charge q=-0.15 c is placed in the electric field. what is the magnitude and direction of the force on the particle?

2.25 N upwards

Explanation:

800 N/C to the right

Explanation:

The equation that relates force on a charge, electric field and charge is

where

F is the force acting on the charge

q is the charge

E is the electric field

In this problem, we have

is the electric field

is the charge

Substituting into the formula, we find the force

Concerning the direction:

- The electric field and the force have same directions if the charge is positive

- The electric field and the force have opposite directions if the charge is negative

Here the charge is negative, so the electric field has opposite direction to the force: therefore, it must be upwards.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

yup its correct its: c) b b
