4. When a train stops suddenly, passengers in the running train feel an instant jerk in the forward direction because (a) The back of seat suddenly pushes the passengers forward (b) Inertia of rest stops the train and takes the body forward (c) Upper part of the body continues to be in the state of motion whereas the lower part of the body in contact with seat remains at rest (d) Nothing can be said due to insufficient data

H C Verma solutions, Introduction to Physics, Objective-II, Chapter-1, Concepts of Physics, Part-I Introduction to Physics

HC Verma Solutions – Concepts of Physics Part 1 – Chapter 1 Objective II HC Verma Solutions – Concepts of Physics Part 1 Chapter 1: Introduction to Physics – Objective II Q1. The dimensions ML⁻¹T⁻² may correspond to: (a) work done by a force (b) linear momentum (c) pressure (d) energy per unit volume Answer: (c), (d) Solution: Work done/energy = Force × distance = [MLT⁻²][L] = [ML²T⁻²] → does not match. Linear momentum = mass × velocity = [M][LT⁻¹] = [MLT⁻¹] → does not match. Pressure = Force / Area = [MLT⁻²] / [L²] = [ML⁻¹T⁻²] → correct. Energy per unit volume = [ML²T⁻²] / [L³] = [ML⁻¹T⁻²] → correct. Q2. Choose the correct statement(s): (a) A dimensionally correct equation may be correct. (b) A dimensionally correct equation may be incorrect. (c) A dimensionally incorrect equation may be correct. (d) A dimensionally incorrect equation may be incorrect. Answer: (a), (b...
