A) \[11{{\Delta }_{1}}=12{{\Delta }_{2}}\]
B) \[12{{\Delta }_{1}}=11{{\Delta }_{2}}\]
C) \[11{{\Delta }_{1}}>12{{\Delta }_{2}}\]
D) None of the above
Correct Answer: B
Solution :
[b] \[{{S}_{1}}=\frac{{{\Delta }_{1}}D}{d}=11\times {{10}^{-3}}\] \[{{S}_{2}}=\frac{{{\Delta }_{2}}D}{d}=12\times {{10}^{-3}}\] \[\Rightarrow {{\Delta }_{1}}/{{\Delta }_{2}}=11/12\Rightarrow 12{{\Delta }_{1}}=11{{\Delta }_{2}}\]You need to login to perform this action.
