Electrical field at the center of a hemisphere

In summary, the electrical field at the center of a hemisphere is radially outward and perpendicular to the surface. It is not affected by the charge distribution, only the total charge. The magnitude can be calculated using E = kQ/R^2. It does not change if the hemisphere is hollow or solid. It can be zero if there is an equal amount of positive and negative charges.

Charge is distributed uniformly on the surface of a hemisphere. Find the electrical field at the center of the sphere due to that.

Can anyone help me?pls ^___^

As a preliminary step, can you determine the direction of the electric field ?
 

Related to Electrical field at the center of a hemisphere

1. What is the direction of the electrical field at the center of a hemisphere?

The electrical field at the center of a hemisphere is radially outward, perpendicular to the surface of the hemisphere.

2. Is the electrical field at the center of a hemisphere affected by the charge distribution of the hemisphere?

No, the electrical field at the center of a hemisphere is only affected by the total charge of the hemisphere and not by its distribution.

3. How do you calculate the magnitude of the electrical field at the center of a hemisphere?

The magnitude of the electrical field at the center of a hemisphere can be calculated using the formula E = kQ/R2, where k is the Coulomb's constant, Q is the total charge of the hemisphere, and R is the radius of the hemisphere.

4. Does the electrical field at the center of a hemisphere change if the hemisphere is hollow or solid?

No, the electrical field at the center of a hemisphere remains the same regardless of whether the hemisphere is hollow or solid, as long as the total charge remains constant.

5. Can the electrical field at the center of a hemisphere be zero?

Yes, the electrical field at the center of a hemisphere can be zero if the hemisphere has an equal amount of positive and negative charges, resulting in a net charge of zero.
