Planck’s constant = J s Force = kg m s2

Q. Few quantities with their units are listed below. Mark the units which are not correctly matched
(i) Density: $k g m^{- 3}$
(ii) Velocity of light : $m s^{- 1}$
(iii) Planck’s constant: $J^{- 1} s^{- 1}$
(iv) Acceleration: $m s^{- 2}$
(v) Force: $k g m$

(ii) and (iv)
