Is the force acting between two point charges `q_(1) and q_(2)` kept at some distance in air, attractive or repulsive when:
`(i) q_(1) q_(2) gt 0`
`(ii) q_(1) q_(2) lt 0`

Text Solution

AI Generated Solution

To determine whether the force acting between two point charges \( q_1 \) and \( q_2 \) is attractive or repulsive based on their product, we can analyze the two given conditions step by step. ### Step-by-Step Solution: 1. **Understanding the Charges**: - We have two point charges, \( q_1 \) and \( q_2 \). - The nature of the force between them depends on whether the charges are like (both positive or both negative) or unlike (one positive and one negative). ...
