Answer:

The value is $v = 1.309*10^{5}\ m/s$

Explanation:

The radius is $r = 7.40 *10^{20} \ m$

The mass of the ordinary matter is $M_{rod} = 1.90 *10^{41}\ kg$

Generally the speed of the star is mathematically represented as

$v = \sqrt{\frac{G * M}{r} }$

Here G is the gravitational constant with a value

$G = 6.67384 * 10^{-11}$

$v = \sqrt{\frac{6.67384 * 10^{-11} * 1.90 *10^{41}}{7.40 *10^{20}} }$

=> $v = 1.309*10^{5}\ m/s$
