One atomic mass unit is equal to `1.67 xx 10^-27 g`.

Define the atomic mass unit?

What is atomic mass unit?

Assuming that protons and neutrons have equal masses,calculate how many times nuclear matter is denser than water.Given that nuclear radius is given by R=1.2 xx 10 ^(-15) A^(1//3) metre and mass of a nucleon = 1.67 xx 10^(-27) kg .

Find de-Broglie wavelength associated with a proton of energy 2 MeV. Given, mass of proton is 1.67 xx 10^(-27) kg .

Calculate the magnitude and direction of the electric field. Which keeps a proton just floating. Give that mass of proton 1.67 xx 10^-27 kg, charge on proton = 1.6 xx 10^-19 C and g = 9.8 ms^-2
