Explanation- a nuclide 1 is said to be mirror isobar of nuclide 2, if Z₁=N₂ and Z₂= N₁

Now ₁₁Na²³, ₁₂Mg²³ for which Z₂=12=N₁ and N₂ =23-12=11=Z₁

(b) As ₁₂Mg²³ contain even number of protons against ₁₁Na²³ which has odd number of protons (11), therefore Mg has greater binding energy than sodium.

Let $\lambda ={10}^{-15}m$

$\lambda =\frac{h}{p}$

and KE= PE

$E=hc/\lambda$ = $\frac{6.6\times {10}^{-34}\times 3\times {10}^8}{{10}^{-15}\times 1.6\times {10}^{-19}}$  eV

K.E= 10⁹eV

Explanation- R= 12dis/min per gm and R₀= 16dis/min per gm T_1/2= 5760yr

R= $e^{-\lambda t}$ $e^{\lambda t}$

By taking log

$\lambda tloge=log\frac{R_0}{R}$

$\lambda t$ = log₁₀16/12 $\times 2.303$

$t=\frac{2.303(log4-log3)}{\lambda }$

= 2.303 (0.6020-4.771)5760/0.6931

  = 2391.20yr

Explanation- during the collision of electron and positron they form gamma radiation and these gamma particle travels in opposite direction to conserve the momentum.

${\displaystyle {\int }_0^{2/3}\frac{dx}{4+9x^2}}equals={\displaystyle {\int }_0^{2/3}\frac{dx}{2^2+{\left(3x\right)}^2}}$

 $=\frac{1}{2}\times \frac{{\left[ta{n}^{-1}\frac{3x}{2}\right]}_0^{2/3}}{3}\\ =\frac{1}{6}\left[ta{n}^{-1}\frac{3}{2}\times \frac{2}{3}-ta{n}^{-1}\frac{3}{2}\times 0\right]\\ =\frac{1}{6}\left[ta{n}^{-1}\left(1\right)-tan\left(0\right)\right]\\ =\frac{1}{6}[\pi /4-0]\\ =\pi /24$
