A charge is distributed along an infinite curved line in space with linear charge distribution λ. What will be the amount of force on a point charge q kept at a certain distance from the line?

• A. q∫\(\frac {\lambda}{r^2}\hat{r}\)dl
• B. q∫\(\frac {\lambda}{r^2}\hat{r}\)dr
• C. q∫\(\frac {\lambda}{r^3}\hat{r}\)dl
• D. q∫\(\frac {\lambda}{r^2}\)
