Dear student
The Planck’s constant (h) can be defined as a proportionality constant that relates the energy (E) of a photon to the frequency (ν) of its associated electromagnetic wave.Mathematically,Planck’s Constant (h) = Energy(E) / frequency (ν).Dimensional Formula of energy = M1L2T-2.Dimensional Formula of frequency = M0L0T-1.Putting these values in above equation we get,Dimensional Formula of Planck’s constant = M1L2T-1.SI unit of Planck’s constant is joule-seconds (j-s).

As the formula of planks constant ,h is h =E/v.That is energy /frequency.The dimension of planks constant is ML^2T^-1.

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
