A 0.410 cm diameter plastic sphere, used in a static electricity demonstration, has a uniformly distributed 35.0 pC charge on its surface. What is the potential (in V) near its surface

The  potential is  

Explanation:

From the question we are told that

     The diameter of the plastic sphere is  

      The magnitude of the charge is  

The radius of the plastic sphere is  mathematically evaluated as

=>    

The  potential near the surface is mathematically represented as

Where k is the Coulombs constant with value

substituting values
