Question

Planet X has free-fall acceleration 8 m/s2 at the surface. Planet Y has twice the mass and twice the radius of 
planet X. On Planet Y

g = 2 m/s2

g = 4 m/s2

g = 8 m/s2

g = 16 m/s2

g = 32 m/s2

Answer 1

is defined as, solution free fall Acceleration g = where a= universal Graudteehonal R? constant Me mass of planet Ra Radius of planet For Planet & 9x = 8 m/s², Эх — a my RAZ 8: to qMx Ry For planet Y My = 2My Ry=2Rx

awb T 12 gy= ㄷ a my Ry 9. (2x) (2Rx) Rx² 2 use eph (0) 2 I 18 Y m/s2 gy lot
