WebIn the case of earth fault conditions, the low earth resistance enables the protection system to isolate the power source and makes the earth potential rise (EPR) less dangerous to humans 4][[5]. To improve the personal safety, the equipment protection and to maintain the continuity of the power supply, buildings have to be pro- WebThe gravitational field inside earth is given by, E= R 3GM ex, where x is the distance of the object from center. As the object moves to center x=0 and therefore, E=0 . The assertion is therefore correct. We know that E= mF= [M][MLT −2]=[LT −2] The reason is also correct. But the reason is not the correct explanation for assertion.

Any potential is … WebIf we assume potential at infinity to be zero and Earth to be spherical then the potential at the surface of the earth is given by k q / r, where k is a constant, q is the charge on earth …
Web2. If we assume potential at infinity to be zero and Earth to be spherical then the potential at the surface of the earth is given by k q / r, where k is a constant, q is the charge on earth and r its radius. As q is extremely small and r very large, the potential at Earth's surface is almost zero. So for all practical purposes we assume its ...
