Hii dear,
◆ Answer-
2×10^30 kg
◆ Explaination-
# Given-
r = 1.5×10^8 km = 1.5 × 10^11 m
T = 365.25 days
T = 365.25×24×60×60 = 31.56×10^6 s
G = 6.67×10^–11 Nm^2/kg^2
# Formula-
Mass of the Sun can be calculated by-
M = 4π^2r^3 / GT^2
M = 4×3.14^2×(1.5×10^11)^3 / (6.67×10^-11×31.56^2×10^12)
M = 2×10^30 kg
Therefore, the mass of the Sun is 2×10^30 kg.
Hope this helps you...
