Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which of the following pairs have same dimensions? (1) Angular momentum and work (2) Torque and work (3) Energy and Young's modulus (4) Light year and wavelengthA) 1, 2 and 3 are correct.
B) 1 and 2 are correct.
C) 2 and 4 are correct.
D) 1 and 3 are correct.
Correct Answer: C
Solution :
Dimensions of angular momentum are\[[M{{L}^{2}}{{T}^{-1}}]\] demensions of work are\[[M{{L}^{2}}{{T}^{-2}}]\] dimensions of torque are\[[M{{L}^{2}}{{T}^{-2}}]\] dimensions of energy are\[[M{{L}^{2}}{{T}^{-2}}]\] dimensions of Young's modulus are\[[M{{L}^{-1}}{{T}^{-2}}]\] dimensions of light year [L] and dimension of wavelength is [L] Therefore, options (2) and (4) are correct.
