Answer :
To determine the correct symbol used in equations to represent the electric force on an object, let's consider the typical symbols used in the context of electromagnetism:
A. [tex]\( q \)[/tex] - This symbol typically represents the charge of an object, measured in coulombs (C).
B. [tex]\( F_e \)[/tex] - This symbol represents the electric force exerted on an object. It is the force that a charged object experiences in an electric field.
C. [tex]\( E \)[/tex] - This symbol commonly represents the electric field strength, measured in volts per meter (V/m).
D. [tex]\( r \)[/tex] - This symbol usually represents the distance between objects or charges, measured in meters (m).
Given these descriptions, the symbol used to represent the electric force on an object is [tex]\( F_e \)[/tex].
Therefore, the correct answer is:
B. [tex]\( F_e \)[/tex]
