Consider two infinitely large plane parallel conducting plates as shown below. The plates are uniformly charged with a surface charge density $$+\sigma$$ and $$-2\sigma$$. The force experienced by a point charge $$+q$$ placed at the mid point between two plates will be:

A

$$\frac{\sigma q}{4 \epsilon_0}$$

B

$$\frac{3\sigma q}{2 \epsilon_0}$$

C

$$\frac{3\sigma q}{4 \epsilon_0}$$

D

$$\frac{\sigma q}{2 \epsilon_0}$$
