Question

The distance of the Sun from Earth is $1.5 × 10^{11}$ $m$ , and its angular diameter is $(2000)$ $s$ when observed from the earth. The diameter of the Sun will be :

A

$2.45 × 10^{10 }$ $m$

B

$1.45 × 10^{10}\; m$

C

$1.45 × 10^9 \;m$

D

$0.14 × 10^9 \;m$

Answer

$1.45 × 10^9 \;m$

Explanation

Solution

The diameter of the Sun will be :

Diameter = $r × δ$

= $1.5×10^{ 11}×(2000)×\bigg(\frac{1}{3600}\bigg)×\bigg(\frac{x}{180}\bigg)$

= $1.45 × 10^9$ $m$
