Answer 1

Answer:

Step 1: Check Option A

As quantities with different dimensions can be multiplied or divided

⇒

N

LM

will be meaningful

Step 2: Check Option B

We can always add or subtract two quantities with the same dimensions.

LN can have dimensions the same as of M

For example : L= mass, N= velocity, M= momentum.

⇒LN−M can be meaningful.

Step 3: Check Option C

LN can have dimension of M

2

For example : L= mass, N= kinetic energy, M= momentum.

⇒

N

LN−M

2

can be meaningful.

Step 4: Check Option D

As L & M have different dimensions, we can never subtract two quantities with different dimensions.

⇒

N

L−M

can never be a meaningful quantity.
