Let \( k_1 \) and \( k_2 \) be circles with the centres \( S_1 \), \( S_2 \), and the radii of lengths \( 5\,\mathrm{cm} \) and \( 1\,\mathrm{cm} \) consecutively. Given \( |S_1S_2|=5\,\mathrm{cm} \), what is the mutual position of these circles?
The circles \( k_1 \) and \( k_2 \) intersect.
The circles \( k_1 \) and \( k_2 \) are internally tangent.
The circles \( k_1 \) and \( k_2 \) are externally tangent.
The circle \( k_1 \) lies inside the circle \( k_2 \).
The circle \( k_2 \) lies inside the circle \( k_1 \).
