Question

A point charge (5.0 pC) is located at the center of a spherical surface (radius = 2.0 cm), and a charge of 3.0 pC is spread uniformly upon this surface. Determine the magnitude of the electric field 1.0 cm from the point charge.

Answer 1

E = 0.45 kN/C

Step-by-step explanation:

From; the question, we can opine that the electric field inside the hollow sphere as a result of the charge at the surface is zero.

Using the equation:

`\mathbf{E = kq/r^2}` to determine the magnitude of the electric field with the radius 1.0 cm from the point charge.

where ;

constant k =
`8.98*10^9`

point charge q = 5.0 pC = 5.0 × 10⁻¹²; we have :

`\mathbf{E = kq/r^2}`

`\mathbf{E =(8.98*10^9*5*10^(-12))/(1.0^2)}`

E = 0.45 kN/C
