Answer:
This process is a simplified model of hydrogen atom consist of an electron revolving abow a proton e a distance of 5-3 X10m The charge on a proton is + 1:6 Xid cacate the intensity of electric field due to proton at this distance and Force.A simplified model of hydrogen atom consist of an electron revolving abow a proton e a distance of 5-3 X10m The charge on a proton is + 1:6 Xid cacate the intensity of electric field due to proton at this distance and Force.A simplified model of hydrogen atom consist of an electron revolving abow a proton e a distance of 5-3 X10m The charge on a proton is + 1:6 Xid cacate the intensity of electric field due to proton at this distance and Force.
