Charge and Mass Invariance

Assertion (A): Both the charge and mass are invariant.
Reason (R): Charge is always associated with mass.
 
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

Solution:

Assertion (A) is true, considering 'mass' as rest mass, which is invariant, similar to charge. Reason (R) is true: All charged particles possess mass; a massless particle cannot carry charge.


(R) is not the correct explanation for (A), as invariance of charge and rest mass are fundamental properties, not directly explained by their association.
