Answer 1

negative charge

Explanation:

a rubber balloon when rubbed against the woolen cloth it acquire a negative charge

Answer 2

The electric charge acquired by a rubber balloon when rubbed with a woolen cloth is negative charge.

Explanation:

• All the matters are neutral as they have equal number of positive charges and negative charges in them.
• The matters are charged due to friction or touch or conduction. When two objects are rubbed then there is frictional force between objects.
• The energy produced by frictional force causes polarity on the matter.
• The rubber balloon gains electron from inflated rubber balloon which makes woolen cloth positively charged due to less number of electrons compared to rubber balloon.
