A) \[7{}^\circ \]
B) \[8{}^\circ \]
C) \[9{}^\circ \]
D) \[10{}^\circ \]
Correct Answer: B
Solution :
\[(n+1){{\delta }_{c}}=(n){{\delta }_{f}}\] \[\therefore \] \[3\times 0\cdot 56\times {{A}_{c}}=2\times 0\cdot 63\times {{A}_{f}}\] \[\Rightarrow \] \[{{A}_{f}}={{8}^{o}}\]You need to login to perform this action.
