A truss consists of horizontal members (AC, CD, DB and EF) and vertical members (CE and DE) having length 1 each. The members AE, DE and BF are inclined at $${45^0}$$ to the horizontal. For the uniformly distributed load ‘p’ per unit length on the member EF of the truss shown in figure given below, the force in the member CD is
A
$${{PL} \over 2}$$
B
$$PL$$
C
Zero
D
$${{2PL} \over 3}$$
