Question

In the figure, if $OC\perp AB,$ then $AC:CB=$

• A. $2$
• B. $1$
• C. $0.5$
• D. $3$

Answer 1

The correct option is B $1$

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The line OC joining the center of a circle to the mid-point of a chord AB is perpendicular to the chord AB.
Hence, $C$ is the mid point of $AB.$
$\therefore AC=CB$
$\frac{AC}{CB}=1$
Answer: $AC:CB=1$
