Hydrogen nucleus and nucleus

a)A hydrogen nucleus and nucleus of an ‘unknown’ atom are stationery, 5.0 x 10-10m apart. The mass of the hydrogen nucleus is mh=1.7 x10-27 kg and the electric charge of the hydrogen nucleus e=1.6x10-19 c. you may assume that the coulomb constant Ke = 9.0 x109 Nm2 C-2 and that gravitational constant G=6.7 x10-11 Nm2 kg-2. i) The Magnitude of electric force between the hydrogen nucleus and the ‘unknown’ Nucleus that is 5.5 x 10-9N. State weather this force is attractive or repulsive. Calculate the electric charge on the ‘unknown’ nucleus that is necessary to give a force of this magnitude express your answer in coulombs using scientific notation. ii) Express the Charge that you have c... click for more
