Question

( begin{aligned} u &=k-k cos a x k &=M L T^{-2} L &=M C^{2} T^{-2} & quad a x=m^{0} L^{0} T^{0} & a=1^{-1} end{aligned} )

# A particle is in a uni-directional potential field where the potential energy (U) of a particle depends on the x-coordinate given by U =k (1-сos ax) & k and 'a' are constants. Find the physical dimensions of a & k.
