A) 1 unit
B) \[\frac{13}{3}\] unit
C) 13 unit
D) None of these
Correct Answer: B
Solution :
The two planes are on the opposite side of the origin. Therefore, if \[{{p}_{1}}\] and \[{{p}_{2}}\] are the lengths of the perpendicular from the origin to the planes \[\mathbf{r}.(\mathbf{i}+2\mathbf{j}-2\mathbf{k})+5=0\] and \[\mathbf{r}.(\mathbf{i}+2\mathbf{j}-2\mathbf{k})-8=0\] respectively, then the required distance is given by \[{{p}_{1}}+{{p}_{2}}=\frac{5}{3}+\frac{8}{3}=\frac{13}{3}\]unit.
