    Hubbles law is expressed as (here, \[\upsilon =\]speed of recession, r = distance of galaxy, H = Hubble constant)

    A)  \[v=Hr\]

    B)         \[v={{H}^{2}}r\]              

    C)         \[v=\frac{H}{{{r}^{2}}}\]                              

    D)         \[v=H{{r}^{2}}\]

    Correct Answer: A

    Solution :

                                    We have,\[v\propto r\] \[\Rightarrow \]               \[v=Hr\] where, H is Hubbles constant.
