10. Give an example of ‘hypothesis concerning Law’.      2

Ans:- Hypothesis concerning law related with the law of operation. Suppose the agent is known but the plan or rule according to which its acts may be unknown in such cases we frame Hypothesis concerning law. To an example from Science Newton knew the agents the Sun, the Earth and Moon but the way they acted upon each other may be unknown, Newton suppose that their motion might be due to their attraction one another in a particular way on the basis of this supposition Newton discovered law of gravitation and law of operation.
