What holds more charge hollow or solid sphere?
A solid conducting sphere holds more charge than a hollow sphere of the same radius when they are at same potential. A solid conducting sphere hold more charge than a hollow sphere of same radius.
Will a solid metal sphere hold a larger charge than hollow sphere of same diameter where does the charge reside in each case?
A solid sphere does not retain more charge than a hollow sphere of the same diameter, because charge resides on the outer surface of a conductor, and outer surface areas of the two spheres are equal.
Does a solid sphere or hollow sphere have a greater moment of inertia?
You should find that a solid object will always roll down the ramp faster than a hollow object of the same shape (sphere or cylinder)—regardless of their exact mass or diameter. (Although they have the same mass, all the hollow cylinder’s mass is concentrated around its outer edge so its moment of inertia is higher.)
Can a solid conducting sphere?
A solid conducting sphere, having a charge Q, is surrounded by an uncharged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V.
Is a hollow metal sphere conductor?
Since the material of which the sphere is made is a conductor, all charges can find their way to the outer surface, whether the interior is hollow or solid. This means that the electric field within the sphere is everywhere zero.
Why is Earth’s potential zero?
Since there is a potential gradient existing between the negative charges on the earth and the positive charges in the atmosphere, a current can flow from the atmosphere to the surface of the earth which neutralises the negative charges on the earth. So the potential associated with the earth is taken as zero.
How can we differentiate between a solid sphere and a hollow sphere?
Solid sphere is 2/5 mr^2 and that of a hollow sphere it is 2/3mr^2. So hollow sphere spins faster. And also the mass is more distributed in a hollow sphere making it easier to spin whereas in a solid sphere it is compact and there is too much mass.
Which has a greater moment of inertia a solid sphere or a solid disk?
Based on the coefficients (2/5 and 1/2), the moment of inertia of solid disk is greater than the moment of inertia of a solid sphere. This phenomenon is caused by the difference in the distribution of mass around the axis.
How is charge distributed in a solid sphere?
Charge on a conductor would be free to move and would end up on the surface. This charge density is uniform throughout the sphere. Charge Q is uniformly distributed throughout a sphere of radius a. That is, the electric field outside the sphere is exactly the same as if there were only a point charge Q.
What is the charge inside a hollow metal sphere?
A hollow metal sphere is electrically neutral (no excess charge). A small amount of negative charge is suddenly placed at one point P on this metal sphere.
Which sphere will hold the same amount of charge?
Both the spheres will hold the same amount of charge. It is because, the two spheres pass equal capacitance. The capacitance of a sphere depends only on its radius. It does not matter whether the sphere is hollow or solid. Was this answer helpful? A solid sphere of radius R is charged uniformly.
How can a solid sphere and a hollow sphere be made?
A solid sphere and a hollow sphere of equal mass and radius are placed over a rough horizontal surface after rotating it about its masss centre with same angular velocity ω0 . Once the pure rolling starts let v1 and v2 be the linear speeds of their centres of mass. Then A solid sphere and a hollow… .
Can a capacitor store more charge in a hollow sphere?
Capacitor can store more charge when kept in a material of high dielectric constant . When a capacitor can’t store more charge it ionise the surrounding thus leading to dielectric breakdown . Therefore hollow sphere and solid sphere of same material and kept in same medium ha same charge storing capacity.
How many times can a solid sphere be expanded inside?
For solid sphere volume coefficient of expansion is taken and for the hollow sphere, areal expansion of coefficient is taken. The volume coefficient is 1.5 times areal coefficient. So it will be 1.5 times expanded in case it is a vacuum inside.
