Gravitational potential at a point inside the earth at a distance r r from the centre of earth is, V = −Gm(3R2 − r2) 2R3 V = - G m ( 3 R 2 - r 2) 2 R … WebIn the previous example, we considered the case in which the earth exerts a force on the ball. We should be able to get the same answer if we consider the case in which the ball exerts …
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. 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-
