1.	Draw a ray diagram of formationof images by the convex lens when object placed between1.Infinity, 2. beyond 2F1
Answer» Solution :(i)RAY diagram for object placed between F and 2F (II)`[OH^-]=1xx10^(-11)` m `pOH=-log_10[OH^-]=-log_10 [10^(-11)]` `=-[-11xxlog_10 10]` =-(-11)=11 pH+pOH =14 pH=14-pOH pH=14-11=3
