Assertion : Force can be subtraced momentum.
Reason : Physical quantities with different mass and dimensions can be subtracte.

Assertion : Force can be subtracted from momentum. Reason : Physical quantities with different dimensions can be subtracted.

Assertion (A) Energy per unit volume and angular momentum can be added dimensionally. Reason (R ) Physical quantities having same dimension can be added or subtracted.

Assertion : The equation y= 2x + t is physical incorrect if x & y are distances and t is time. Reason : Quantities with different dimension cannot be added or subtracted.

Assertion : The equation y= 2x + t is physical incorrect if x & y are distances and t is time. Reason : Quantities with different dimension cannot be added or subtracted.
