Q. 1

The dimensions ML A. work done by a force

B. linear momentum

C. pressure

D. energy per unit volume.

Answer :

(a) work done by the force:


work done = force × distance


= [ML1T-2] * [L]


work done = ML2T-2


(b) linear momentum:


p = mv


= [M] [LT-1]


Linear momentum = MLT-1


(c) pressure:



= /L-2


pressure = ML-1T-2


(d) energy per unit volume




E = ML-1T-2
