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.

E = 0.45 kN/C

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:

 to determine the magnitude of the electric field with the radius 1.0 cm from the point charge.

where ;

constant k =

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

E = 0.45 kN/C

the total distance traveled by the car is

30km + 49km = 79 km .
