A heavy nucleus N, at rest, undergoes fission N goes to P+Q, where P and Q are two lighter nuclei. Let delta=M(N)-M(P)-M(Q), where N(N), M(P), M(Q) are the masses of N, P, and Q respectively. E(P) and E(Q) are the kinetic energies of P and Q respectively. The speeds of P and Q are vP and vQ. If c=speed of light, which of the following statement(s) is (are) correct?
A) E(P)+E(Q)=c^2(delta)
B) E(P)={M(P)/[M(P)+M(Q)]} c^2(delta)
C) vP/vQ=M(P)/M(Q)
D) The magnitude of the momentum for P as well as Q is c[(2u(delta)]^(1/2).
