Calculate the wavelength (in nanometer) associated with a proton moving at 1.0 x 10³ ms⁻¹ (Mass of proton = 1.67 $$\times$$ 10^-27 kg and h = 6.63 $$\times$$ 10^-34 Js) :

In an atom, an electron is moving with a speed of 600 m/s with an accuracy of 0.005%. Certainity with which the position of the electron can be located is (h = 6.6 $$\times$$ 10^-34 kg m²s^-1, mass of electron, e_m = 9.1 $$\times$$ 10^-31 kg)
