ELECTROSTATICS LAB. PLEASE HELP TO ANSWER THESE QUESTIONS> PLEASE> ASAP
In the experiment you are asked to touch the charged object with your hand whenever you need to neutralize its charge What does this accomplish the task? Is there any possibility that the task in question (1) is not accomplished'? (Yes or No} How could you guaranty that touching the charged object with your hand neutralizes that'? How could you learn about the relative charge accumulation in a rod. which is rubbed with different fabrics when you interact it with another charged rod? Why do you the experiment charging the end of the rods?Explanation / Answer
1. whenever there is a charged particle it acts like a open voltage sourse (or current source). SO, when you touch the partice your body to ground forms a close circuit which can easily pass the accumulated charges to current in terms of current. Thus the chrage becomes neutral.
2. It might possible if there is a possibility of insulation betwwn the charge and ground. Like shoes, Hand gloves may cause insulation to the circuit and the charge can't flow out to the ground.
3.the best way to neutralize acharged particle is to connenct it to the ground using metal wire. It will gurantee that the chrage is neutral. In case of body with poen foot to the ground and open hand touching the particle for reasonable time may certify that the charge is neutral.
4. When to charge body comes near there will be elecrical communications(opposite charge will attract and the same charge will repale). For very low charge accumulation te phenomenon may not be obsevable but as you increase the charge (by rubbing) you can obsrve spaking when the two rod are close enough.
5.
The experimemt is done at the ned of the rod because at the ned the area of the rod is minimum and thus the charge density is maximum. charge density
qd = Q/A---------1, where A is the area of the charged particle.
