Apoint charge is placed at each corner of a square with side length a. the charges all have the same magnitude q. two of the charges are positive and two are negative, as shown in the following figure. q: what is the magnitude of the net electric field at the center of the square due to the four charges in terms of q and a?

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

i believe the answer is electric potential.

explanation:

at right angles to each other
