The mean distance of sun from the earth is 1.5 × 108 km nearly. The time taken by the light to reach earth from the sun is: (A) 0.12 min (B) 8.33 min (C) 5 min (D) 13 min

As we know t=(s/v) t=(1.5 × 108 × 1000/3 × 108 × 60) t=(500/60)=8.33 min

Q. The mean distance of sun from the earth is $1.5 \times 1 0^{8} km$ nearly. The time taken by the light to reach earth from the sun is:

$0.12 min$

$8.33 min$

$5 min$

$13 min$

As we know
$t = \frac{s}{v}$
$t = \frac{1.5 \times 1 0 ^{8} \times 1000}{3 \times 1 0 ^{8} \times 60}$
$t = \frac{500}{60} = 8.33 min$
