Question

The power obtained in a reactor using U235 disintegration is 1000 kW. The mass decay of U235 per hour is (A) 10 microgram (B) 20 microgram (C) 40 microgram (D) 1 microgram

E = Pt = mc 2 m =( Pt / c 2)=(106 × 3600/(3 × 108)2) m =40 μ gm

Q. The power obtained in a reactor using $U^{235}$ disintegration is $1000 kW$ . The mass decay of $U^{235}$ per hour is

10 microgram

20 microgram

40 microgram

1 microgram

$E = Pt = m c^{2}$
$m = \frac{Pt}{c ^{2}} = \frac{1 0 ^{6} \times 3600}{( 3 \times 1 0 ^{8} ) ^{2}}$
$m = 40 μg m$
