The acceleration due to gravity o the surface of earth is

g = GM / R2.......................................................(i)

Let at a height h from the surface of earth, the acceleration due to gravity is 4% of its value on the surface of earth.

Then, 0.04g = GM / (R+h)2..........................(ii)

from (i) and (ii) ,

h = 4 R

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
