MCQ: Force that acts on a mass of 1 g and gives it an acceleration of 1 cms-2 is defined as
- 1 newton
- 1 dyne
- 1 pound-force

MCQ: Einstein's mass-energy relationship states that if mass decreases by Δm, energy released ΔE is given by
- ΔE = Δm × c, where "c" denotes the speed of light.
- ΔE = Δm × c², where "c" denotes the speed of light.
- ΔE = Δm ⁄ c, where "c" denotes the speed of light.
- ΔE = Δm ⁄ c², where "c" denotes the speed of light.
MCQ: When work done in moving a particle round a closed loop in a field is zero, forces in field are called
- Zero forces
- Non-Conservative forces
- Conservative forces
- Viscous forces
MCQ: Dimensions of relative density are
- mass × length-3
- mass × length³
- It has no dimensions, since it's a ratio of two densities
