What does path independence of line integral physically mean?
For a physical meaning, take potential energy as an example. To raise an object from one position to another position one meter higher takes a certain amount of energy - the potential energy of the object increases. The amount of energy is independent of the path the object takes - whether it goes straight up, in zigzag, etc.
If you want to lift a 5kg box to the height of meter how much work must be done?
Did you say one meter ?You'll have to give the box 49 joules of additional gravitational potential energy.But since the human muscular system is not 100% efficient, you'll have to spendsomewhat more energy than that in order to do the job. The additional energythat you put into the effort will show up in the form of elevated body temperature,increased heart rate and blood pressure, and warm perspiration on your brow.
What is The Function of Meter?
it is use to measure electric potential (voltage).
What is potential gradient?
The rate of change of potential with respect to distance is called potential gradient. its unit is volt per meter or newton/coulomb.
