The values of the acceleration due to gravity on two planets are `g_(1) - g_(2)`, then the two planets must have the sameA. raduisB. massC. `(("mass")/("radius"))^(2)`D. `("mass")/(("radius")^(2))` |
|
Answer» Correct Answer - D For any planet, `g=(GM)/(R^(2))" " therefore g_(1)=g_(2)` `therefore (GM_(1))/(R_(1)^(2))=(GM_(2))/(R_(2)^(2)) " " therefore (M_(1))/(R_(1)^(2))=(M_(2))/(R_(2)^(2))` `therefore` The two planets must have the same value of `("Mass")/(("Radius")^(2))`. |
