Electrostatics
When an ebonite rod is rubbed with wool, they get oppositely charged due to conduction. Explain
The electric charge developed on glass rod rubbed with silk cloth is different from the charge developed on ebonite rod rubbed with fur.
When glass rod is rubbed with silk cloth, it acquires positive charge.
But when ebonite rod is rubbed with fur, the rod gets negatively charged.
So, charge developed on glass rod rubbed with silk is different from charge developed on ebonite rod rubbed with fur. Hence this statement is true.
When an ebonite rod is rubbed with wool, they get oppositely charged due to conduction. Explain
When a glass rod is rubbed with silk, the charge acquired by the silk is :
Which of the following is NOT a correct method of the preparation of benzylamine from cyanobenzene?
In free space, a particle A of charge $$1 \, \mu C$$ is held fixed at a point P. Another particle B of the same charge and mass $$4 \mu g$$ is kept at a distance of $$1 \, mm$$ from P. if B is released, then its velocity at a distance of $$9 mm$$ from P is : [Take $$\dfrac{1}{4 \pi \varepsilon_0} = 9 \times 10^9 Nm^2 C^{-2}$$]
Name two substances which can be charged by friction.
A woolen cloth when rubbed against plastic object acquires ______ charge.
A glass rod when rubbed with silk cloth, acquires a charge of $$1.6\times 10^{-11}C$$, then the charge on silk cloth will be:
An ebonite rod held in hand can be charged by rubbing with flannel but a copper rod cannot be charged like this. Why?
When a polythene piece is rubbed with wool, it acquires negative charge.
Which of the following statement is NOT true?
