A. 0.01
B. 0.1
C. 10
D. 100
Answer: Option B
Solution (By Examveda Team)
$$\eqalign{ & \Leftrightarrow \frac{{0.13}}{{{p^2}}} = 13 \cr & \Leftrightarrow {p^2} = \frac{{0.13}}{{13}} \cr & \Leftrightarrow {p^2} = \frac{1}{{100}} \cr & \Leftrightarrow p = \sqrt {\frac{1}{{100}}} \cr & \Leftrightarrow p = \frac{1}{{10}} \cr & \Leftrightarrow p = 0.1 \cr} $$This Question Belongs to Arithmetic Ability >> Square Root And Cube Root
