Equipotential surface: Any surface that has same electric potential at every point on the surface of the conductor known as equipotential surface.
Ampere’s Circuital law: The line integral of the magnetic field around any closed circuit is equal to the µ0 times the total current l threading or passing through the closed circuit.

Position
The position of a particle refers to its location in the space at a certain moment of time.
It is concerned with the question - “ where is the particle at a particular instant of time ? ”
Velocity: Rate of change of position with time is called velocity.
(a) It is a vector quantity
If a particle is accelerated with constant acceleration in an interval of time, then the motion is termed as uniformly accelerated motion in that interval of time.For uniformly accelerated motion along a straight line, following equations can be used

Motion With Uniform Velocity
Consider a particle moving along x-axis with uniform velocity u starting from the point x =xi at t = 0.
Equations of x, v, a are : x (t) = xi + ut ; v (t) = u ; a (t) = 0

Position.
Position of an object or point is expressed in terms of co-ordinates.Position of any point is completely expressed by two factors: Its distance from the observer and its direction with respect to observer.
That is why position is characte
