MCQ
Earth’s potential is _______?
  • A
    Zero.
  • B
    Highly positive.
  • C
    Highly negative.
  • D
    Varies from place to place.
✓

Answer

  1. Zero.

Explanation:

We consider earth as the storage of infinite positive as well as a negative charge. Therefore, the potential of the earth is always considered to be zero and the potential of every body is measured with respect to earth. That’s why if we connect any charged body to the earth, its potential instantaneously becomes zero.
