(i) volumetric strain and coefficient of friction |
(ii) disintegration constant of a radioactive substance and frequency of light wave |
(iii) heat capacity and gravitational potential |
(iv) Planck's constant and torque |
The correct pairs are |
A) (i), (ii) and (iii)
B) (i), (ii) and (iv)
C) (iii) and (iv)
D) (ii) and (iii)
Correct Answer: A
Solution :
[a] (i) strain and coefficient of friction both are dimensionless (ii) disintegration constant and frequency of light both have dimensions \[[{{T}^{-1}}]\] (iii) heat capacity has unit \[cal/kg\]while gravitational potential has unit J/kg i.e. both have dimensions \[[{{L}^{2}}{{T}^{-2}}]\].You need to login to perform this action.
