What is the electric field of a uniformly charged sphere?
The electric field of a uniformly charged sphere is the same as that of a point charge located at the center of the sphere. This means that the electric field is radially outward from the center of the sphere and its magnitude decreases as you move away from the center.
What is the distribution of the electric field inside a charged sphere?
The electric field inside a charged sphere is uniform and directed radially towards the center of the sphere.
The Electric Field inside and outside a Charged Insulator?
Inside a charged insulator, the electric field is 0, as charges cannot move freely in insulators. Outside the insulator, the electric field behaves as if all the charge is concentrated at the center of the insulator.
What will be the electric field intensity at the center of a hollow charged sphere?
The electric field intensity at the center of a hollow charged sphere is zero. This is because the electric field created by the positive charges on one side of the sphere cancels out the electric field created by the negative charges on the other side, resulting in a net electric field of zero at the center.
What is the electric field outside a charged spherical shell?
Outside a charged spherical shell, the electric field behaves as if all the charge is concentrated at the center of the shell. This is known as Gauss's Law for a spherical surface, which states that the electric field at a distance r from the center of a charged spherical shell is equivalent to that of a point charge with the same total charge as the shell at the center. Therefore, the electric field outside a charged spherical shell decreases with the square of the distance from the center of the shell.
How can the motion of a charge particle be used to distinguish between a magnetic field and an electric field in a certain region?
The motion of a charged particle in a magnetic field will experience a force perpendicular to both the particle's velocity and the magnetic field direction, causing it to move in a circular path. In contrast, in an electric field, the particle will accelerate in the direction of the field. By observing the path of the charged particle, one can determine whether it is in a magnetic field (circular motion) or an electric field (accelerating linear motion).
Does Every charged object produces an electric field that is parallel to its surface?
No, not every charged object produces an electric field parallel to its surface. The orientation of the electric field depends on the distribution of charge on the object and its shape. The electric field can point in any direction depending on the configuration of the charges.
What is the difference in the electric field inside and outside a charged insulator?
The electric field inside a charged insulator is zero, while the electric field outside a charged insulator is non-zero.
What is the difference between the electric field and the electric force in the context of electromagnetism?
The electric field is a region around a charged object where other charged objects experience a force. The electric force is the actual force experienced by a charged object in an electric field. In summary, the electric field sets up the conditions for the electric force to act on charged objects.
What is the relationship between the electric field produced by a point charge and a charged sphere?
The electric field produced by a point charge is directly proportional to the charge and inversely proportional to the square of the distance from the charge. For a charged sphere, the electric field outside the sphere behaves as if all the charge is concentrated at the center, similar to a point charge. Inside the sphere, the electric field is zero.
How is a charged particle accelerated when the electric field inside the dees of a cyclotron is zero?
In a cyclotron, the charged particle is accelerated by the oscillating electric field between the dees. When the particle enters the gap between the dees, the electric field is zero, but a magnetic field causes the particle to rotate in a circular path and gain energy each time it crosses the gap due to its velocity being increased by the electric field before entering the gap.
What is the formula for calculating the electric field of a charged sphere?
The formula for calculating the electric field of a charged sphere is E k Q / r2, where E is the electric field, k is the Coulomb's constant (8.99 x 109 N m2/C2), Q is the charge of the sphere, and r is the distance from the center of the sphere.
