Q173 of 196 Page 249

The distance between the Sun and the Earth is 1.496 × 1011 km and distance between the Earth and the Moon is 3.84 × 108 m. During solar eclipse the Moon comes in between the Earth and the Sun. What is distance between the Moon and the Sun at that particular time? (Question given is wrong, corrected.)


From the problem, SE = 3.84 × 1011 m


ME = 1.496 × 108 m


SM = x m


SM = SE-ME


3.84 × 1011 m - 1.496 × 108 m


3.84 × 1011 m – 0.001496 × 1011 m


3.84 × 1011 m – 0.001496 × 1011 m


SM = 3.838 × 1011 m
