Question

Hubbies law is expressed as u= speed of recession, r= distance of Galaxy and H = Hubbies constant) : (A) v=(H/r2) (B)  upsilon =(H/r)  (C)  upsilon =Hr  (D)  upsilon =Hr2

According to Hubble's law, speed of recession is directly proportional to the distance of galaxy i.e. v propto r ⇒ v = Hr where, H is Hubble's constant.

Q. Hubbies law is expressed as $u =$ speed of recession, $r =$ distance of Galaxy and $H =$ Hubbies constant) :

$v = \frac{H}{r ^{2}}$

$υ = \frac{H}{r}$

$υ = Hr$

$υ = H r^{2}$

According to Hubble's law, speed of recession is directly proportional to the distance of galaxy i.e.
$v \propto r$
$\Rightarrow v = Hr$
where, $H$ is Hubble's constant.

Q. Hubbies law is expressed as u= speed of recession, r= distance of Galaxy and H= Hubbies constant) :

v=r2H​

υ=rH​

υ=Hr

υ=Hr2
