Question
Chapter 16, Problem 9Q
To determine
What balances the electric force of repulsion so that the leaves of an electroscope don’t separate further?
Expert Solution & Answer
Answer to Problem 9Q
Solution:
The leaves of the electroscope do not separate further, because the electric force of repulsion is equal to the gravitational force. This balances the electric force.
Explanation of Solution
The leaves of the electroscope do not separate further, because the electric force of repulsion is equal to the gravitational force. Thus the gravitational force balances the electric force.Gravitational force pulling down on the leaves, and hence tending to return them to the vertical position.
