Q. Uranium 238 nucleus, initially at rest, emits an Alpha particle with the speed of 1.4*10^7 metre per second. Calculate the recoil speed of the residual nucleus Thorium 234 resume that mass of the nucleus is proportional to the mass number

Q. A $U^{238}$ nucleus, initially at rest, emits an alpha particle with a speed $v_0$. The recoil speed of the residual nucleus $T{h}^{234}$ is $\frac{x}{y}{v}_0$. Find $(y-x)$. Assume that the mass of a nucleus is proportional to the mass number.

Q. A nucleus (mass no. $238$) initially at rest decay into another nucleus (mass no. $234$) emitting an $\alpha$ particle (mass no. $4$) with the speed of $1.17\times {10}^{7}m/sec$. Find the recoil speed of the remaining nucleus.

Q. A nucleus ( mass no. 238 ) initially at rest into another nucleus ( mass no 234 ) emitting an $\alpha$ particle (mass no-4) with the speed of$1.17\times {10}^7$m/sec. Find the recoil speed of the remaining nucleus.

Q. When $U^{238}$ nucleus originally at rest, decays by emitting an alpha particle having a speed $u$, the recoil speed of the residual nucleus is
