Gravity on the surface of sun is given as
[tex]g = \frac{GM}{R^2}[/tex]
here we know that
[tex]M = 1.98 \times 10^{30} kg[/tex]
[tex]R = 6.95 \times 10^8 m[/tex]
now we will have
[tex]g = \frac{(6.67 \times 10^{-11})(1.98 \times 10^30)}{(6.95 \times 10^8)^2}[/tex]
[tex]g = 273.4 m/s^2[/tex]
now we need to find the ratio of weight on surface of sun and on surface of Earth
[tex]R = \frac{mg_{sun}}{mg_{earth}}[/tex]
[tex]R = \frac{273.4}{9.8} = 28 times[/tex]
so weight will increase by 28 times
