Five Styrofoam balls A,B,C,D, and E are used in an experiment. The following observations were made in this experiment :

I. Ball A repels C and attracts B.

II. Ball D attracts B and has no effect on E.

III. A negatively charged rod attracts both A and E.

Based on the above information, answer the following questions:

The ball E must be

• A. Positively charged
• B. Negatively charged
• C. Neutral
• D. Can't say

Answer 1

The correct option is C

Neutral

The explanation for the correct answer

C. Neutral

1. When Ball D attracts B, the ball E remains constant.
2. Though the negatively charged rod attracts A and E, A becomes positively charged.
3. So, ball D becomes Neutral.

Hence, the correct option is C.

Therefore, the ball E must be option C Neutral.
