Assertion : If the units of force and length are doubled, the unit of energy will be 4 times. Reason : The unit of energy is independent of the unit of force and length.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Energy \(=\) force \(\times\) distance; so when the units of force and length or distance are doubled the unit of energy will become 4 times that of its initial value. So correct option is (3)

If \(u_{1}\) and \(u_{2}\) are the units selected in two systems of measurement and \(n_{1}\) and \(n_{2}\) are numerical values, then
Physical quantity \((p)=\) Numerical value (n) \(\times\) Unit \((u)\). If physical quantity remains constant then \(n \propto 1 / u \quad \therefore n_{1} u_{1}=n_{2} u_{2}\).
