Chapter 22: Q. 11 (page 624)

You have two neutral metal spheres on wood stands. Devise a procedure for charging the spheres so that they will have like charges of exactly equal magnitude. Use charge diagrams to explain your procedure.

Short Answer

Expert verified

Charge a neutral sphere with a charge rod then bring another neutral sphere and touch the charged sphere to get the same charge and magnitude on both of them.

Step by step solution

Content Introduction

On top of an insulating stand, a neutral conducting sphere is at rest. A negatively charged tube is brought close to the neutral sphere (without touching it). The electrons are forced to travel from the left to the right side of the sphere by the presence of the negatively charged tube.

Content Explanation

Charges may be transferred from a charged to a neutral object. As a result, we proceed to the next stages in order to obtain two sphere-like charges of equal magnitude.

To begin, we connect a charged rod to a neutral sphere.
The charge transfer between the rod and the sphere will charge the sphere.
After then, bring another neutral sphere with the same size and form as the charged one and make contact with it. Charges will be transferred to a neutral sphere.
The charge and magnitude of the green neutral sphere will be the same as the blue sphere. Then immediately separate both spheres to ensure that they have the same charge and magnitude.

We can look at the following picture:
