Answer:
Coulomb's law
Explanation:
The correct answer is Coulomb's law and it deals with particles which undergo interactions based on their electric charges.
It states that the electrostatic force acting between two charged particles is directly proportional to the product of the charges of the two particles and is inversely proportional to the square of the distance between them.
The constant of proportionality is called Coulomb's constant.
Mathematically, it is given as:
where k = Coulomb's constant
q = charge of first particle
Q = charge of second particle
r = distance between both particles

Answer:
.
Explanation:
If the mass of an object is and the velocity of that object is
, the linear momentum of that object would be
.
Assume that the initial velocity of the mass is positive (.) However, the direction of the velocity is reversed after the impact. Thus, the sign of the new velocity of the object would be negative- the opposite of that of the initial velocity. The new velocity would be
.
Thus, the change in the velocity of the mass would be:
.
The change in the linear momentum of the mass would be:
.
Thus, the magnitude of the change of the linear momentum would be .
