Assertion: The physical quantity defined by rate of doing work is Energy.
Reason: Its SI unit is J/s.
The correct answer is option (d) Assertion (A) is false but reason (R) is true.
Explanation:
- The assertion states that the physical quantity defined by the rate of doing work is energy. However, this is incorrect. The physical quantity defined by the rate of doing work is power, not energy. Power is the rate at which work is done or the amount of work done per unit time.
- Power is defined as the rate at which energy is transferred or converted. It is the amount of energy transferred or converted per unit time. The SI unit of power is the watt (W), which is equal to one joule per second (J/s).
- Energy, on the other hand, is the capacity to do work. It is a scalar quantity and is measured in joules (J). Energy can be transferred or converted from one form to another, but the rate at which this energy is transferred or converted is power.
- Therefore, the reason given that the SI unit of power is J/s is true, but the assertion that the physical quantity defined by the rate of doing work is energy is false.
In conclusion, option (d) is the correct answer as it correctly identifies that the assertion is false but the reason is true.
