A) \[{{\theta }_{i}}+{{\theta }_{c}}={{\theta }_{n}}\]
B) \[{{\theta }_{i}}-{{\theta }_{c}}=2{{\theta }_{n}}\]
C) \[\frac{{{\theta }_{i}}+{{\theta }_{c}}}{2}\theta n\]
D) \[{{\theta }_{c}}-{{\theta }_{i}}=2{{\theta }_{n}}\]
Correct Answer: C
Solution :
\[{{\theta }_{n}}-{{\theta }_{c}}={{\theta }_{i}}-{{\theta }_{n}}\] or \[{{\theta }_{n}}=\frac{{{\theta }_{i}}+{{\theta }_{c}}}{2}\]You need to login to perform this action.
