Questions
Suppose two deuterons must get as close as 10-14 m in order for the nuclear force to overcome the repulsive electrostatic force. The height of the electrostatic barrier is nearest to
detailed solution
Correct option is A
deutron is having one proton + one neutron so charge of deutron is 1.602×10-19 CBarrier height =14πε0e2reJ=14πε0ereeV =9×109×1.6×10−1910−14eV=1.44×105eV =0.14MeVTalk to our academic expert!
