Correct answer: C
-
Find dimensions of each quantity in List-I
We match each physical quantity with its dimensional formula.
-
(A) Angular Impulse
Angular impulse = torque time.
Torque has dimensions:
Therefore,
So,
-
(B) Latent Heat
Latent heat here means heat energy required per unit mass.
Heat (energy) has dimensions:
Hence latent heat (specific latent heat):
So,
-
(C) Electrical resistivity
Resistivity is given by:
Resistance:
Potential difference has dimensions:
Therefore,
Now,
So,
-
(D) Electromotive force
Electromotive force has same dimensions as potential difference:
So,
-
Final matching
This corresponds to Option C.
-
Comparison with stored answer
Stored correct answer = C
Our derived answer = C
Hence, they agree.
