A) \[\frac{4}{\sqrt{1-{{m}^{2}}}}\]
B) \[\frac{4}{\sqrt{{{m}^{2}}-1}}\]
C) \[\frac{4}{\sqrt{{{m}^{2}}+1}}\]
D) \[\frac{4m}{\sqrt{1+{{m}^{2}}}}\]
E) \[\frac{4m}{\sqrt{m-1}}\]
Correct Answer: C
Solution :
Equation of line is \[y=mx+4\] \[\therefore \]Required distance\[=\frac{4}{\sqrt{1+{{m}^{2}}}}\]
