MCQ
The dimensions of power are
  • ${M^1}{L^2}{T^{ - 3}}$
  • B
    ${M^2}{L^1}{T^{ - 2}}$
  • C
    ${M^1}{L^2}{T^{ - 1}}$
  • D
    ${M^1}{L^1}{T^{ - 2}}$

Answer

Correct option: A.
${M^1}{L^2}{T^{ - 3}}$
a
(a) Power = $\frac{{{\rm{Work done}}}}{{{\rm{Time}}}} $$= \left[ {\frac{{M{L^2}{T^{ - 2}}}}{T}} \right] = [M{L^2}{T^{ - 3}}]$
