Electric Force and Electric Field problem

In summary, the conversation discusses a honeybee acquiring a charge while flying and the electric field near the surface of the Earth. Two questions are posed, one about the ratio of electric force to weight on the bee and the other about what electric field strength and direction would allow the bee to hang suspended in the air. Relevant equations are also listed. The individual is unsure about how to solve the problem and asks for assistance.

Homework Statement



A 0.15 g honeybee acquires a charge of 18 pC while flying. The electric field near the surface of the Earth is typically 100 N/C, directed downward.

What is the ratio of the electric force on the bee to the bee's weight?
What electric field strength and direction would allow the bee to hang suspended in the air?


Homework Equations



E=F/q
F=k|q1q2|/r^2
W=mg

The Attempt at a Solution



Weight of bee = 9.8 * .15g
I honestly have no idea on how to begin this problem. I would appreciate any help!

Thanks!

Do you know what "N/C" means? Do you know what the electric field is?
 

1. What is the difference between electric force and electric field?

Electric force refers to the attraction or repulsion between two charged particles, while electric field refers to the region around a charged particle where it can exert a force on other charged particles.

2. How is electric force calculated?

Electric force is calculated using Coulomb's law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

3. What factors affect the strength of an electric field?

The strength of an electric field is affected by the magnitude of the charge creating the field, the distance from the charge, and the medium (material) that the field is passing through.

4. How do electric fields and electric forces impact the behavior of charged particles?

Electric fields and electric forces play a crucial role in determining the motion of charged particles. They can cause particles to accelerate, change direction, or remain at rest depending on their charge and the direction of the field.

5. How are electric fields and electric forces used in everyday life?

Electric fields and electric forces are used in a variety of everyday applications, such as powering electronic devices, generating electricity, and even in medical treatments like electrocardiograms. They also play a crucial role in understanding and manipulating the behavior of atoms and molecules in chemistry and biology.
