Question

Select the correct option given below:
In given figure, the minimum distance to reach from point 'C' to point 'A' will be_______.

• A. $a^2$
• B. $\sqrt{2}$
• C. $2$
• D. $2a$

Answer 1

The correct option is D $2a$

From the given figure,
$\cos {60}^o=\frac{AB}{AC}$
$\therefore \frac{1}{2}=\frac{AB}{AC}$
$\therefore AC=2a$
$\therefore$ the minimum distance to reach from point 'C' to point 'A' $=AC=2a$.
