questions in about 10 words: true and false
Answers
Answer:
2.
When you rub an ebonite rod against a cloth the rod gets negatively charged and the fur gets positively charged. This is because some of the atoms of the ebonite rod is deposited to the cloth. Thus, making it negative and increasing the no.
3.
Repulsion is possible only both the bodies are charged either +vely or -vely . Hence, repulsion is the sure test of a magnet. it is definite proof for both bodies being charged as it indicates the attraction or repulsion of the magnet, as negative charge and positive charge.
4.
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.
5.
It is false that electroscope is a device which is used to charge a body by induction. - Electroscope is an old scientific device which was basically used to detect the presence of electrical charge in a body.
