. A solid plastic sphere of radius 10 cm has charge with uniform density throughout its volume. The electric field 5 cm from the center is 86 kN/C radially inward. Find the magnitude of the electric field 15cm from the center. (Answer: 76.4KN/C)
Added by Karim S.
Step 1
First, we need to find the charge density (Ļ) of the sphere. We can use the formula for the electric field inside a uniformly charged sphere: E = (Ļ * r) / (3 * εā) where E is the electric field, r is the distance from the center, and εā is the vacuum Show moreā¦
