# NEET Physics Nuclei Questions Solved

In the given nuclear reaction A, B, C, D, E represents
${}_{92}{}^{238}\mathrm{U}\stackrel{\mathrm{\alpha }}{\to }{}_{\mathrm{B}}{}^{\mathrm{A}}\mathrm{Th}\stackrel{\mathrm{\beta }}{\to }{}_{\mathrm{D}}{}^{\mathrm{C}}\mathrm{Pa}\stackrel{\mathrm{E}}{\to }{}_{92}{}^{234}\mathrm{U}$

(a) A = 234, B = 90, C = 234, D = 91, E = $\mathrm{\beta }$
(b) A = 234, B = 90, C = 238, D = 94, E =$\mathrm{\alpha }$
(c) A = 238, B = 93, C = 234, D = 91, E = $\mathrm{\beta }$
(d) A = 234, B = 90, C = 234, D = 93, E = $\mathrm{\alpha }$
