Centripetal acceleration question confirmation please

[pinnacleprouk]

Homework Statement

what is the magnitude and direction of the centripetal acceleration necessary to confine the motion of a 0.5kg mass moving at speed 0.1m/s to a circular path 0.2m in radius

Homework Equations

a = v^2/r

The Attempt at a Solution

0.1^2/0.2 = a

a = 0.05m/s/s towards the centre

Doesn't look right to me

Thanks in advance
