Solution

The correct option is C 6 cm and 10 cm

Locus is the path traced by a moving point, which moves so as to satisfy the certain given condition/conditions.

Here the given circle is of radius 8 cm. The locus of a point which is at a distance of 2 cm from this circle can be:-

a circle of radius = 8 - 2 = 6 cm

a circle of radius = 8 + 2 = 10 cm
