Answer: Lk for this plasmid = 47 
Explanation:
The formula to compute Lk is given by :-
Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)
Given: A plasmid 41 twists and 6 right handed writhes. 
i.e. Twist (Tw) = 41   , Writhe (Wr) = 6
Then, Topological Linking Number (Lk) for this plasmid :  = 41+6
= 47
Hence, the Lk for this plasmid = 47
