Question

what is positive or negative absolute potential? ​

Answer 1

Answer:

$\huge \underline \mathfrak \red{Answer}$

The absolute potential at a point is the work done against electric forces in carrying a unit positive test-charge from infinity to that point. Hnece the absolute potential at a point B is the difference in potential from A = ∞ to B.

Answer 2

Answer:

The absolute potential at a point is the work done against electric forces in carrying a unit positive test-charge from infinity to that point. Hnece the absolute potential at a point B is the difference in potential from A = ∞ to B.

At a separation of the surface of Earth (r=6400km) gravity wants pull the test mass closer and closer. ... So the work done by gravity is NEGATIVE. The gravitational potential energy is negative because us trying to do the opposite of what gravity wants needs positive energy.
