Question

The dimensions ML−1 T−2 may correspond to
(a) work done by a force
(b) linear momentum
(c) pressure
(d) energy per unit volume.

Answer 1

Answer:

the correct ans is (c) because Pressure is force divided by area the dimensions of force are MLT-2 and of area are L-2 this when we divide them we get it

Answer 2

Explanation:

(a) Work done by a force :-

Work done = force x distance

= [ML 1 [L]

=ML?T2

(b) Linear momentum :

p= mv

= [M][LT ]

=MLT1

(c)Pressure :

P=F/A

= [ML-2][L]

=ML-'T-2

(d)Energy per unit volume

E = (force x displacement)/volume

=[MIT-21L]/[L )

= ML-17-2

Hence (C) & (d) is the correct option whose

dimension is ML-11-2
