Question

Define electrostatics potential at a point . Write it's s.I unit?




three point charges q1 ,q2 and q3 are kept at vertices a, b and c of triangle respectively. Derive the




expression for the electrostatics potential energy of system. If ab = r12 , bc = r23 and ac = r13

Answer 1

Answer:

Explanation:

electric potential at a point is defined as the amount of work done in moving a unit positive charge from infinity to that point against the direction of electric field.

s.i. unit=volt(V).

Answer 2

Electrostatic potential:

An electric potential (also known as the electric field potential, potential drop or the electrostatic potential) is the amount of work required to move a unit of charge from a reference point to a specific point inside the field without generating acceleration.  

SI unit:

Its SI unit is volt.

Expression for electrostatic potential energy:

$U_{E} = \frac{q1q2q3}{r}$
