Which two methods of charging objects involve touching?
Two methods of charging objects that involve touching.
Answer to Problem 16A
Two methods of charging objects that involve touching are friction and contact.
Explanation of Solution
Introduction:
According to the charge conservation principle, the number of charges in any interaction remains constant. They neither produce nor destroy.
Methods that involve the transfer of charge when both objects touch each other are:
Charging by friction: In this method, both objects are not charged. But, due to rubbing action, both objects become charged.
Charging by contact: In this method, one object is charged and it is brought near and made contact with an uncharged object. This way, charges are induced in the uncharged surface and it also becomes charged.
Conclusion:
Thus, two methods of charging objects involve touching are friction and contact.
