A stone of mass m is tied to a string of length l and rotated in a circle with a constant speed v. If the string is released, the stone flies :
radially outward
radially inward
tangentially
with an acceleration mv2/l

Solution:

In Circular motion velocity of the particle is always directed along tangent. So when string is released object moves tangentially.
