in q7 of mcq test(static electricity) the answers are 1 and 3.when i answered the option 1 it came wrong.y?electroscopes are used to detect if the object is conductor or not na
Q11.
Use the following information to answer the next question.
Three charged metal spheres, I, II, and III are made up of the same metal. The amount and the nature of charge possessed by each ball are shown in the given figure.
Sphere I can be made positively-charged by touching it with sphere
II only
III only
II first and then with sphere III
III first and then with sphere II
What is quantum nature of charge?
repulsion is the surest test for electrification explain
what is electrostatic force
Why does the lightening conductor have so many spikes, if it would have worked well with only one?
wh is static electricity?
name three constituents of an atom and state the kind of charge on them.
petrol tanks along the highways often have metal chains attached that drag along the road.why?

i am not understanding the sums in static electricity
what is substanceare
why the direction of an electric current is taken as opposite to the direction of an electric charge ?
why is repulsion the surest test of electrification?
The difference between lightning conductor and the process of earthing ?
chose the odd one out with reasoning

If you take off your woollen sweater inside a dark room, you will be able to see sparks. These sparks occur due to the presence of electric charges. What is the reason behind it?
dear meritnation experts in the chapter static electricity, in topic lightening just the name of video which is VIDEO:13012 is written but the video is not given so please provide that vedio asfaster as you can , because I have my UNIT TEST tommorow.
why earthed conducting sheets are used around the lower half of the gold leaf electroscope?
how does the comb gets charged on combing dry hair?
how does electric charges come in woolen sweaters?
the charge on a body is +1C. Find the number of electrons in excess or deficit on the body

are there any requirements in the computer to watch the videos with 3D tag?
the charge on a body is +1 c.Find the number of electrons in excess or deficit on the body
when a glass rod is rubbed with silk,what kind of charge is acquired by each.explain.
what will happen if the glass rod and refill are rubbed with polythene?
The given figure shows three charged metal spheres made up of the same material. Sphere I is first touched with sphere II and then touched with sphere III.
What will be the amount of charge remaining on sphere I?
Two positive charges
Two negative charges
One positive charge
One negative charge
Ans :
When sphere I is brought in contact with sphere II, a total of electrons will get transferred to sphere II in order to distribute the charges evenly on both the spheres. This process of charging is called charging by conduction. Therefore, after the transfer of electrons, sphere I will have (9 6) = 3 negative charges.
When a contact is made between spheres I and III, a total of electrons will get transferred from sphere I to sphere III in order to make the electron distribution equal on both the spheres. Therefore, after the transfer of electrons, sphere I will be left with (5 3) = 2 positive charges.
The correct answer is A.
