The electric conductor having excess of electrons is said to be at a negative or lower potential and the conductor having deficit of electrons is said to be at a positive or higher potential. Thus the electrons flow from the conductor at lower potential to the conductor at higher potential.

## Which plate has higher electric potential?

The positive plate is at a higher potential than the negative plate. Field lines and equipotential lines for a constant field between two charged plates are shown on the right.

## What does the positive and negative sign of a potential convey?

The positive sign of potential conveys that work has to be done on the positive test charge against the repulsive force due to the positive charge in bringing it from infinity. The negative sign of potential conveys that work is done on the negative test charge by the attractive force.

## Is potential energy on the surface of Earth always zero?

The nature of potential energy is that the zero point is arbitrary; it can be set like the origin of a coordinate system. This is an approximation which is only valid near the surface of the earth, but is fine for baseballs and other common applications of gravitational potential energy.

## What is the potential energy on the surface of Earth?

Near the surface of the Earth, the work done in lifting an object through a height h is the product mgh , so U=mgh . The gravitational potential energy, U , of a system of masses m1 and M2 at a distance r using gravitational constant G is U=−Gm1M2r U = − G m 1 M 2 r .

## What is positive work Negative work and zero work?

Positive work done – The work done is said to be positive when force and displacement are in the same direction. Hence, work is positive. Zero work – the work done is said to be zero when force and displacement are perpendicular to each other.

## What do you mean by positive negative and zero work?

So,work done is positive. NEGATIVE WORK:The work done is said to be negative work when force and displacement are in opposite direction. ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero.

## What are the conditions that determine whether the work done is positive negative or zero?

The SI unit for work and energy is the joule (J), where 1 J = 1 N ⋅ m = 1 kg ⋅ m2/s2. The work done by a force is zero if the displacement is either zero or perpendicular to the force. The work done is positive if the force and displacement have the same direction, and negative if they have opposite direction.
