(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

Q. 1

The dimensions ML A. work done by a force

B. linear momentum

C. pressure

D. energy per unit volume.

Class 11th HC Verma - Concepts of Physics Part 1 1. Introduction to Physics

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

= /L^-2

∴ pressure = ML^-1T^-2

(d) energy per unit volume

∴ E = ML^-1T^-2
