A) \[\frac{3}{2}\]
B) \[\frac{5}{2}\]
C) \[\frac{7}{2}\]
D) \[\frac{9}{2}\]
Correct Answer: C
Solution :
Planes are \[2x+y+2z-8=0\text{ }\And \text{ }2x+y+2z+\frac{5}{2}=0\] Distance is \[=\frac{\frac{5}{2}-(-8)}{\sqrt{{{2}^{2}}+{{1}^{2}}+{{2}^{2}}}}=\frac{\frac{21}{2}}{3}=\frac{7}{2}\]You need to login to perform this action.
