The figure shows five point charges on a straight line. Separation between successive charges is $$10\,\text{cm}$$. For what values of $$q_1$$ and $$q_2$$ would the net force on each of the other three charges be zero

A

$$q_1=q_2=-\frac{27}{80}\,\mu\text{C}$$

B

$$q_1=q_2=\frac{27}{40}\,\mu\text{C}$$

C

$$q_1=\frac{27}{80}\,\mu\text{C},\ q_2=-\frac{27}{80}\,\mu\text{C}$$

D

$$q_1=q_2=-\frac{27}{40}\,\mu\text{C}$$
