Question

4. (10 points) A spherical non-conducting balloon has a uniform positive charge on its surface. The balloon in expanded. a. (5 points) What happens to the magnitude of the electric field at a radius that remains outside the balloon before and after it is expanded? It will: I. Increase II. Decrease III. Remain the same b. (5 points) What happens to the magnitude of the electric field at a radius that at the beginning is outside the balloon and after expansion is inside the balloon? It will: I. Increase II. Decrease III. Remain the same

Step 1

a. **Electric field at a radius outside the balloon:** The electric field \( E \) due to a uniformly charged spherical surface at a point outside the sphere is given by: \[ E = \frac{kQ}{r^2} \] where \( k \) is Coulomb's constant, \( Q \) is the total charge Show more…
