Nuclear energy is energy that is stored in the core of a certain type of atom. Atoms are the smallest units of matter and they make up everything in our universe. Energy is what causes the core of an atom to stay together and inside the core, there is vast amounts of energy.
when an object is revolving in circular path then its velocity is always along the tangent of the circular path
so while moving in circular path if the string is break then due to law of inertia the object will always move in the direction of initial motion
As we know that as per law of inertia if an object will not change its state of motion or state of rest until some external force will act on it.
So here also the object will move along its tangential direction once the string will break
so here the correct path will be
Option B
