Two point charges \(+6 \mu \mathrm{C}\) and \(+10 \mu \mathrm{C}\) kept at certain distance repel each other with a force of 30 N . If each charge is given an additional charge of \(-8 \mu \mathrm{C}\), the two charges
- A Attract with a force of 2 N
- B repel with a force of 2 N
- C Attract with a force of 15 N
- D repel with a force of 15 N
Answer & Solution
Correct Answer
(A) Attract with a force of 2 N
Step-by-step Solution
Detailed explanation
\(\mathrm{F}=\frac{\mathrm{kq}_1 \mathrm{q}_2}{\mathrm{r}^2} \Rightarrow 30=\frac{\mathrm{k}(6)(10)}{\mathrm{r}^2} \Rightarrow \frac{\mathrm{k}}{\mathrm{r}^2}=\frac{1}{2}\) Now, it \(-8 \mu \mathrm{c}\) charge given on indivisual charge then,…
