1.	79. A planet has a mass M, and radius Ri. The value of acceleration due to gravityon its surface is g. There is anotherplanet 2, whose mass and radius bothare two times that of the first planet.Which one of the following is theacceleration due to gravity on thesurface of planet 2?(a) g1(b) 2g1c)g1/2(d) g1/4
Answer» OPTION CEXPLANATION:g₁=GM/R²g₂=2GM/(2R)² =2GM/4R²g₁:g₂=GM/R² : 2GM/4R² =1:1/2the value of g becomes 1/2 the previous valuehope it helped and pls mark as BRAINLIEST:)
