The mass of earth is 80 times that of moon. Their diameters are 12800 km and 3200 km respectively. The value of g on moon will be, if its value on earth is `980cm//s^(2)`A. `98cm//s^(2)`B. `196cm//s^(2)`C. `100cm//s^(2)`D. `294cm//s^(2)` |

Answer» Correct Answer - b `(g_(2))/(g_(1))=(m_(2))/(m_(1))xx((R_(1))/(R_(2)))^(2)` `=(1)/(80)xx((12800)/(3200))^(2)=(1)/(80)xx16=(1)/(5)` `(g_(2))/(g_(1))=(980)/(5)=196cm//s^(2)`. |
