Describe an experiment to demonstrate that there are two $$ r $$ kinds of charges.
Aim-To Show that there are two kind of charges.
Appratus - gold leaf electroscope, glass rod rubbed with silk cloth.
any two non-identical bodies say $$ A $$ and $$ B $$.
Procedure -
(i) Charge the gold leaf electroscope positively by touching it with glass rod rubbed with silk cloth.
(ii) The gold leaf electroscope shows its charging by showing its leaves diverging.
(iii) Touch the brass cap of this electroscope with body A-note the divergence of the gold leaves.
(iv) Now touch the brass cap with body band note the divergence.
Observation - In case of body A - leaves further diverge.
In case of body $$ B $$ 0 Leaves converge.
Inference - Body $$ A $$ (positively charged)
Body $$ B $$ ( negatively charged )
So there are two types of charges
Three identical metal plates with large surface areas are kept parallel to each other As shown in figure. The leftmost plate is given a charge $$Q$$, the rightmost a charge $$-2Q$$ and the middle one remain neutral. Find the charge appearing on the outer surface of the rightmost plate.
A soap bubble is given a negative charge, then its radius
Two identical conducting sphere, fixed in place, attract each other with an electrostatic force of $$0.108\ N$$ when their center-to-center separation is $$50.0\ cm$$. The sphere are then connected by a thin conducing wire. When the wire is removed, the sphere repel each other with an electrostatic force of $$0.0360\ N$$. Of the initial charges on the sphere, with a positive net charge, what was the negative charge on one of them?
Calculate the number of coulombs of positive charge in $$250\ cm^{3}$$ of (neutral) water. (Hint: A hydrogen atom contains one pro eight protons.)

If a cat repeatedly rubs against your cotton slacks on a dry day, the charge transfer between the cat hair and the cotton can leave you with an excess charge of $$-2.00 \mu C$$. Just before the spark appears, do you induce positive or negative charge in the faucet?
Following figure shows four situations in which positive and negative charges moves horizontally through a region and gives the rate at which each charge moves. Rank the situations according to the effective current through the region greatest first
The number of electrons and protons in an atom are same.
In induction, a positively charged body can make an uncharged body positively charged.
What are the two kinds of charges?
