Answer:
If the mass of a proton is 1.67×10−271.67×10−27 kg and the mass of an electron is 9.11×10−319.11×10−31 kg. Calculate the force of gravitation between; (1) A proton and an electron (2) Two electrons (3) Two protons.
Take G=6.67×10−11Nm2kg−2G=6.67×10−11Nm2kg−2, Distance between the protons =4.0 m=4.0 m, Distance between the proton and the electron =5.4∗10−11
