A small piece of dust of mass m = 3.8 mu or micro g (micrograms) travels through an electric air cleaner in which the electric field is 526 N/C. The electric force on the dust particle is equal to the weight of the particle.
(a) What is the charge on the dust particle?
Homework Equations
F=ma
q=F/E
The Attempt at a Solution
((3.8*10^-9)*9.81)/526=7.079*10^-11
An electric field is an invisible force field that surrounds an electrically charged object. It is created by the interaction of positive and negative charges and can exert a force on other charged particles within its range.
An electric field can cause a dust particle to experience a force or movement based on its charge. If the dust particle is positively charged, it will be attracted towards the negatively charged end of the electric field. If the dust particle is negatively charged, it will be repelled from the negatively charged end of the electric field.
The movement of a dust particle through an electric field is influenced by the strength of the electric field, the charge of the dust particle, and the presence of any other charged particles or objects in the surrounding environment.
An electric field can be used to attract or repel dust particles in a specific direction, allowing scientists to control their movement and behavior. This can be useful in various scientific experiments, such as studying the properties of dust particles or creating new materials.
Yes, there can be potential dangers, especially if high voltage electric fields are involved. Dust particles can become charged and accumulate in certain areas, potentially causing electrical discharges or sparking. It is important to take proper safety precautions when working with electric fields and dust particles.
