The charge of a sphere refers to the amount of electric charge it carries, which can be positive or negative. The charge of a sphere affects its electrical properties by determining how it interacts with other charged objects. Positively charged spheres repel other positively charged objects and attract negatively charged objects, while negatively charged spheres repel other negatively charged objects and attract positively charged objects. This interaction is governed by the principles of electrostatics.

What are the properties of a charged sphere with a cavity?
A charged sphere with a cavity has the property that the electric field inside the cavity is zero. This means that any charge placed inside the cavity will not experience any electric force. The electric field outside the sphere behaves as if all the charge is concentrated at the center of the sphere.
What is the amount of charge on the sphere?
The amount of charge on the sphere is the total electric charge present on the surface of the sphere.
What is the formula for calculating the charge density of a sphere?
The formula for calculating the charge density of a sphere is Q / V, where is the charge density, Q is the total charge of the sphere, and V is the volume of the sphere.
What happens to the charge on the conductive sphere when it is connected to a source of charge?
When a conductive sphere is connected to a source of charge, the charge will distribute itself evenly across the surface of the sphere. This is because charges repel each other and will spread out to achieve maximum separation. The overall charge on the sphere can change depending on the charge from the source and the existing charge on the sphere.
What is the surface charge density formula of a sphere?
The surface charge density formula of a sphere is Q / 4r, where is the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.

What is the formula for calculating the surface charge density of a sphere?
The formula for calculating the surface charge density of a sphere is: Q / 4r, where represents the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
What is the characteristic length of a sphere and how does it affect the sphere's properties?
The characteristic length of a sphere is its diameter, which is the distance across the sphere passing through its center. The characteristic length affects the sphere's properties such as volume, surface area, and density. A larger characteristic length means a larger volume and surface area, while a smaller characteristic length means a smaller volume and surface area.
Suppose two identical spheres are given charges of 4g and -g respectively if they are brought into electrical contact and then separated what charge is retained by each sphere?
After they are brought into contact and then separated, the charges will redistribute themselves evenly, resulting in each sphere having a charge of 1.5g.
Will a solid metal sphere hold greater charge then a hollow sphere of the same diameter where does the charge reside in each case?
No, the charge of a hollow sphere and a solid sphere of the same diameter will be the same as long as they are both made of the same material. In both cases, the charge resides on the outer surface of the sphere due to electrostatic repulsion.
What is the electric field of an insulating sphere?
The electric field of an insulating sphere is the force per unit charge experienced by a charge placed at any point outside the sphere. It is determined by the distribution of charge on the surface of the sphere and follows the same principles as the electric field of a point charge.
What is the relationship between the voltage inside a uniformly charged sphere and the distribution of charge within the sphere?
The voltage inside a uniformly charged sphere is directly related to the distribution of charge within the sphere. As the charge distribution becomes more uniform, the voltage inside the sphere becomes more evenly distributed. This means that the voltage is higher towards the center of the sphere where the charge is concentrated, and decreases towards the surface where the charge is spread out.
