Consider three charged bodies P,Q and R. If P and Q repel each other and P attracts R, what is the nature of force between Q and R ?

Options

A. Repulsive force
B. Attractive force
C. No force
D. None of these

Answer

To determine the nature of the force between the charged bodies Q and R, we can analyze the information given in the problem step by step.

### Step 1: Analyze the interaction between P and Q
- The problem states that P and Q repel each other. This indicates that both P and Q must have the same type of charge. They could either both be positively charged or both be negatively charged.

### Step 2: Analyze the interaction between P and R
- The problem also states that P attracts R. For P to attract R, R must have an opposite charge compared to P. If P is positively charged, R must be negatively charged, or if P is negatively charged, R must be positively charged. Additionally, R could also be neutral, which would still result in attraction due to the electric field created by P.

### Step 3: Determine the charge of Q
- Since we established that P and Q repel each other and both have the same charge, we can conclude that Q must also be positively charged if P is positively charged, or negatively charged if P is negatively charged.

### Step 4: Determine the nature of the force between Q and R
- Now we consider the charges of Q and R:
- If P is positively charged, then Q is also positively charged, and R is negatively charged (or neutral).
- In this case, a positively charged Q would repel a negatively charged R, leading to a repulsive force.
- If R is neutral, then Q will still attract R due to the electric field of Q.

### Conclusion
- Therefore, since Q is positively charged and R is negatively charged (or neutral), the nature of the force between Q and R will be attractive.

### Final Answer
The nature of the force between Q and R is attractive.
