SI units of energy – Rankers Physics

Units: Practice Problem & Solution

Assertion (A): eV and joule are the S.I. units of energy used in modern physics and mechanics respectively. Reason (R): Different types of energies require different units in S.I. units.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Units. Understanding the underlying formula is key to arriving at the correct answer below:

The SI unit of all forms of energy is the joule. Electron-volt (eV) is not an SI unit, and different forms of energy do not require different SI units.
