1.	If the ratio of the orbital distance of two planets (d_1)/(d_2)=2, what is the ratio of gravitational field experienced by these two planets?
Answer» SOLUTION :Given:`(d_1)/(d_2)=2` FORMULA:Gravitational FIELD, `E=(GM)/(d^2)` `(E_2)/(E_1)=(((GM)/(d_(2)^(2))))/(((GM)/(d_(1)^(2))))=((d_1)/(d_2))^(2)=(2)^(2)` `(E_2)/(E_1)=4` `E_(2)=4E_(1)`
