How will you use a pith ball electroscope to find out whether the charge on a charged body is positive or negative?

Answer

Using Pith ball electroscope, we can determine the type of charge on the body by following the below steps:.

  1. Take a charged pith ball electroscope. Let it be positively charged.
  2. Bring the charged body near the pith ball without touching it.
  3. If the pith ball moves away, the body has positive charge.
  4. If the pith ball moves towards the body, the body has negative charge.
