Answer 1

Answer:

When an object is touched with the metal top of an electroscope, its aluminium leaves diverge. What conclusion do you get from this observation? Answer : If the leaves of the electroscope diverge or open up when an object is touched, the body is charged.

Answer 2

Aluminium leaves of electroscope:

• Electroscope is used to determine the presence of electricity.
• Leaves are present in gold leaf electroscope.
• When a charged object is brought near electroscope, the charge of the metal rod polarises its charges.
• If the object is negatively charged and when it is brought near electroscope, the upper part of the metal rod in electroscope becomes positively charged and lower part of the electroscope becomes negatively charged.
• Since, two leaves attached at the bottom of the rod has same charges, so, both leaves repels.
