Physics - W.E.P. Question with Solution | TestHub

A particle moves with a velocity$\left(5\hat{\mathrm{i}}-3\hat{\mathrm{j}}+6\hat{\mathrm{k}}\right){\text{m s}}^{-1}$under the influence of a constant force$\overrightarrow{F}=\left(10\hat{\mathrm{i}}-10\hat{\mathrm{j}}+20\hat{\mathrm{k}}\right)\text{N.}$The instantaneous power applied to the particle is
