Imagine two separated tiny interacting uniformly charged spheres. What happens to the electrostatic force on each of them if the charge on one is doubled?
Thechanges in the electrostatic force between two tiny charge spheres separated by a distance if charge on one of the spheresis doubled.
Answer to Problem 17SP
Solution:
Force on both the charges will also double.
Explanation of Solution
Given data:
The charge on one sphere is doubled.
Formula used:
Write the expression for electrostatic force for any point charge by another point charge:
Here,
Explanation:
Consider the expression for the electrostatic force between twopoint charges:
Here,
Now, consider the expression for the electrostatic force between twopoint charges. This time charge
Here,
The force
Conclusion:
Therefore, the electrostatic force on both the charges is doubled when change on one of the sphere is doubled.
