matlab The electric potential around a charged particle is given by , where ε=8.854x10-12V=14πrqC/Nm2 , q is the charge and r is the distance from the particle. The electric potential of 2 particles at a point P is given by , where q1 and q2 are the particles charges and r1 and r2V=14π(q1r1+q2r2)are distances from the particles to P. Two particles with charges q1=2x10-10 C and q2=3x10-10 C are located in the x-y plane at (0.25,0) and (-.25,0). Calculate and plot the electric potential due to the particles at points in the x-y plane located in the domain -0.3<=x<=0.3 and -0.3<=y<=0.3.

By dividing you can find the answer

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
