Question

explain electrostatic potential, force and capacitance..!​

Answer 1

Answer:

__________________________❤

Electrostatic potential:-

it is amount of work done used to move a object from a point to another point

____________________________❤

force:-

Push or pull on an object

____________________________❤

capacitance :-

Ability to a system to store an electric charge

Answer 2

SOLUTION.

1. ELECTROSTATIC POTENTIAL

FIRSTLY YOU NEED TO KNOW WHAT THE MEANING OF POTENTIAL IS. POTENTIAL ENERGY IS THE ENERGY STORED IN THE SYSTEM WHEN IT MOVE AGAINST A CONSERVATIVE FORCE. BUT WHEN UNIT MASS MOVES AGAINST THE CONSERVATIVE FORCE THAN THE POTENTIAL ENERGY IN THIS CASE BECOME POTENTIAL.

SO POTENTIAL IS THE AMOUNT OF ENERGY STORED BY THE UNIT MASS SYSTEM WHEN MOVE AGAINST CONSERVATIVE FORCE.

IN THIS WORLD WE HAVE MILLIONS OF CONSERVATIVE FORCES ALONG WITH CONSERVATIVE FIELD. ELECTRIC FIELD IS SUCH A CONSERVATIVE FIELD.

SO ELECTROSTATIC POTENTIAL IS THE POTENTIAL DEFINED FOR ELECTRIC FIELD MEANS THE ENERGY STORED IN THE SYSTEM OF UNIT CHARGE WHEN MOVE AGAINST ELECTRIC FIELD. (WITH ZERO VELOCITY)

2.FORCE

FORCE IS SOME WHAT VERY FAMILIAR CONCEPT OR TERM IN CLASSICAL PHYSICS.

YOU HEARD MANY A TIME THAT "PUSH OR PULL BY THE BODY ON ANOTHER BODY IS KNOWN AS FORCE" OH COME ON THIS IS 8th CLASS DEFINITION.

FORCE IS A FACTOR DUE TO WHICH WE CAN CHANGE THE STATE OF ANY BODY HAVE MASS.

FROM STATE I MEAN STATE OF REST OR MOTION .

FOR EXAMPLE.....

IF A STONE IS RESTING ON THE SURFACE IF WE APPLY FORCE ON IT THAN THE STONE START MOVING HENCE ITS STATE CHANGES (FROM REST TO MOTION).

3. CAPACITANCE

LET WE CHARGE A CONDUCTOR WITH SOME CHARGE ( LET SAY Q) SO DUE TO THIS CHARGE WORK IS HAS TO BE DONE TO MOVE A ELECTRON FROM ONE POINT OVER ITS SURFACE TO ANOTHER. V BE THE AMOUNT OF WORK DONE TO MOVE A ELECTRON.

AS Q INCREASES V ALSO INCREASES .

SO Q IS DIRECTLY PROPORTIONAL TO V

Q=CV

WHERE C IS THE CONSTAÑT NAMELY CAPACITANCE.
