Which equation is used to calculate the electric potential in an electric field from a point charge? V = kq over d squared V = kq over d V =delta U over q V = delta U over E

The answer is V=kq/d

Explanation:

The electrostatic potential is defined in terms of work done in taking a unit positive charge from infinity to the point in question.

V=kq/d

Where d= distance from infinity to the point in question

k= constant of proportionality

q= attracting charge

The electric potential is measured in volts

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the answer would be 32*f
