Find the dimestion of Planck's constant.

The ratio of the dimensions of Planck’s constant and that of the moment of inertia is the dimension of-

The dimensional formula for Planck’s constant is :

The work function of a metallic surface is 2.5 eV. Ultraviolet light of wavelength 2000Å is allowed to be incident on the metallic surface. Calculate Stopping potential. (Given Planck's constant h = 6.63 xx 10^(-34) J-s , electronic charge e = 1.6 xx 10^(-19) C, electron mass m = 9.1 xx 10^( -31) kg
