The charges each of +Q and -Q coulomb are placed at corners A and B of an equilateral triangle ABC of side 'a'cm. 'D' is the mid point of AB. The work done if a charge of 'q' is moved from D to C is:

A

zero

B

`(1)/(4 pi epis_0 ) xx qQ`

C

`(Q )/( 4 pi epis_0) xx ( sqrt(3))/(2) q `

D

`(Q) /( 4 pi epsi_0 ) xx sqrt(3) q`
