A conducting sphere 45 cm in diameter carries an excess of charge, and no other charges are present. You measure the potential of the surface of this sphere and find it to be 14 kV relative to infinity. Find the excess charge on this sphere.

The excess charge is

Explanation:

From the question we are told that

      The diameter is

       The potential of the surface is

The radius of the sphere is  

substituting values

The potential on the surface is mathematically represented as  

Where k is coulomb's constant with value  

  given from the question that there is no other charge the Q is the excess charge  

Thus  

substituting values

the answer is a. at the equator

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
