Which equation is used to calculate the electric potential in an electric field from a point charge?

The electric potential (voltage) produced by a point charge , at any point in space, is given by the following equation:

Where:

is the Coulomb's constant

is the distance  

The result is a scalar quantity, is defined as the electric potential energy per unit of charge and determines the electric influence exerted by the charge on that point of space.

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

the bal will not change its velocity.
