When a body is earth connected, electrons from the earth flow into the body. This means, the body is

Options

  1. Auncharged
  2. Bcharged positively
  3. Ccharged negatively
  4. Dan insulator

Correct answer

B. charged positively

Step-by-step solution

Earth is considered to be source of infinite charges having zero potential. When a body is connected to earth, it also acquires same potential as Earth i.e. zero. By this process excess charges flow through the body to the ground or the body acquires the opposite charges from the ground to make the body electrically nevtral. Thus, electrons flow from earth to the body to neutralise the positively charged body.
