Our sun with mass 2 xx 10^(30)kg revolves on the edge of our milky way galaxy which can be assumed to be spherical having 10^(20)m Also assumee that many stars identical to our sun are unifromly distributed in the spherical milky way galaxy If the time period of the sun is 10^(15) second and number of stars in the galaxy are nearly 3 xx 10^((a)) find value of 'a' (take pi^(2) = 10, G (20)/(3) xx 10^(-11) inMKS) .
