A) 60 cm and 30 cm
B) 60 cm and 90 cm
C) 20 cm and 40 cm
D) 40 cm and 60 cm
Correct Answer: B
Solution :
\[\because \] \[n\propto \frac{1}{l}\] \[\therefore \] \[AP:PQ:QB=\frac{1}{1}:\frac{1}{2}:\frac{1}{3}\] \[=6:3:2\] \[AP=\frac{6}{6+3+2}\times 110=60\,cm\] \[PQ=\frac{3}{6+3+2}\times 110=30\,cm\] \[\therefore \] \[AQ=90cm\]You need to login to perform this action.
