A positively charged object attracts a suspended light conducting sphere. The light conducting sphere can be
I. Negatively charged
II. Positively charged
Ill. Neutral

Options

A. I only
B. II only
C. II and III only
D. I and lII only.

Explanation

To solve the problem, let's analyze the situation step by step.

### Step 1: Understand the Charges
We have a positively charged object and a suspended light conducting sphere. The question asks what charge the sphere can have if it is attracted to the positively charged object.

**Hint:** Remember that opposite charges attract each other, while like charges repel.

### Step 2: Analyze the Possible Charges on the Sphere
The sphere can be:
1. Negatively charged
2. Positively charged
3. Neutral

We need to determine which of these charges would allow the sphere to be attracted to the positively charged object.

**Hint:** Think about the nature of attraction and repulsion between different types of charges.

### Step 3: Consider the Case of a Negatively Charged Sphere
If the sphere is negatively charged, it will be attracted to the positively charged object. This is consistent with the principle that opposite charges attract.

**Hint:** This is a straightforward case; think about how charges interact.

### Step 4: Consider the Case of a Positively Charged Sphere
If the sphere is also positively charged, it would repel the positively charged object. Therefore, this scenario cannot occur if the sphere is to be attracted.

**Hint:** Remember that like charges repel each other.

### Step 5: Consider the Case of a Neutral Sphere
If the sphere is neutral, it can still be attracted to the positively charged object. This is due to the phenomenon of electrostatic induction, where the positive charge of the object induces a negative charge on the side of the sphere closest to it, resulting in attraction.

**Hint:** Think about how neutral objects can still interact with charged objects through induction.

### Conclusion
From the analysis:
- The sphere can be negatively charged (attraction occurs).
- The sphere can be neutral (induction causes attraction).
- The sphere cannot be positively charged (repulsion occurs).

Thus, the correct options for the charge of the suspended light conducting sphere are:
- I. Negatively charged
- III. Neutral

### Final Answer
The light conducting sphere can be negatively charged or neutral.

**Correct Options:** I and III.
