Question

If 1 g of hydrogen is converted into 0.993 g of helium in a thermonuclear reaction, then the energy released in this reaction will be: (A)  0.63× 1010J  (B)  6.63× 1014J  (C)  63× 1010J  (D)  0.63× 107J

Δ m=1-0.993=0.007 gm ∴ E=(Δ m) c2=(0.007 × 10-3)(3 × 108)2 =63 × 1010 J

Q. If $1 g$ of hydrogen is converted into $0.993 g$ of helium in a thermonuclear reaction, then the energy released in this reaction will be:

$0.63 \times 10^{10} J$

$6.63 \times 10^{14} J$

$63 \times 10^{10} J$

$0.63 \times 10^{7} J$

$Δ m = 1 - 0.993 = 0.007 g m$
$∴ E = (Δ m) c^{2} = (0.007 \times 1 0^{- 3}) (3 \times 1 0^{8})^{2}$
$= 63 \times 1 0^{10} J$
