Zero maximum force (N) or field strength (N/C). ... minimum /maximum field strength.
Unless if all forces cancel each other out , the object will no longer be in equilibrium
Answer:
Relative velocity is nothing but the velocity of one body with respect to the velocity of some other body.
Explanation:
Relative velocity may be defined as the rate at which the change of separation takes place between any two object.The relative velocity of any object A w.r.t. another object B when they are in motion is nothing but the rate of change of their position from one another.
Now, let the velocity of object A be 
and velocity of object B is 
Therefore, relative velocity of a object A when compared to the velocity of object B is given by
.
