thoron's mass is 220 u can check that in internet i bet that there is some mistake in this question maybe some priting mistake.A stationary thoron nucleus (A=200,Z=90)emits an alpha particle with kinetic energy Ealpha(Ea).which is the Kinetic Energy of the recoiling nucleus?
A: Ea/108
B: Ea/110
C: Ea/54
D: Ea/55
E: Ea
Please can anyone solve this?
mass is inversely proporntional to k.e
mass k.e
4 Ea
216 x
x= (Ea*4)/216
x=Ea/54
